  1. Hi guys, hopefully someone out there in GM world can help me. I'm installing an aftermarket running board lights which has courtesy lights and turn signal lights. I looked every where to get some concrete answer where i can tap into the OEM parking lights wire, courtesy light wire, and turn signal wire. Now, I realize i can run them into the hood and into each headlamp but I much rather keep the connections neat inside the cab. I looked at the GMUPFitter manual and quite honestly it might as well be in chinese to me. If any one has any info with pictures broken down Barney style I would appreciate it. Also if you recommend not tapping into any wire coming from the BCM then where would be the best place to tap into? Thanks in advance to everyone who is willing to help! @pgamboa any suggestions?
  2. $70 to ship within the 48 States.
  3. So I purchased a 98 sierra 1500. Drove it around for a few days before I realized the front speakers in the door didn't have any sound. So, i did what any other sane man would do, and replaced the speakers. Theres still no sound. The stereo was already replaced with the duel din out of my previous truck. So it's not that. Correct me if I'm wrong, but the only thing left to replace would be the wiring correct?
  4. I have a 2017 Chevy Silverado 3500 HD High Country with 6.6 diesel equipped with tow package. It has dedicated trailer brake and trailer fuses within the primary fuse box under the hood. My passenger side trailer blinkers and brake lights are not working. I've traced the lack of 12v power all the way up to the 10a fuse dedicated to the right side trailer brake/signal light (fuse #17). I have replaced the fuse, re-tested, and still no power. The left side trailer brake/signal light (fuse #14) has 12v power going to it, tested on the top of the fuse when the flashers are on, but the right side has nothing. I've also swapped and then replaced the trailer parking lights relay switch (relay #63) and still nothing. Is this most likely an issue with fuse box or something else supplying power or ground to the fuse box? Thanks for the help... this is the craziest thing.
  5. 2019 Silverado 2500HD , BEST WAY TO PERMANENTLY RUN WIRES FOR EMERGENCY CAB MOUNTED BEACON REQUIRING MULTIPLE SWITCHES. ANOTHER SAME TYPE VEHICLE WITCH REQUIRES ONLY ONE SWITCH.
  6. 2019 Silverado 2500 HD ,Looking for way to permanently run wires to cab roof emergency light beacon that needs multiple switches. Also on another same model one switch.
  7. I have a 2017 Silverado 1500 LTZ that came with factory LED tail lights. I recently bought a set of Morimoto XB LED tail lights that are not intended for factory LED trucks. I also purchased a set of tail light harness for a non-LTZ Silverado (GM Part #’s 23295977 and 23295978) so it would be a plug and play installation. Everything works (running lights, brake lights, reverse) but I have hyper flash on the turn signals. I have more pics and video of the issue on my instagram - @pgsulins Here is a list of the things I unsuccessfully tired to correct the issue: 1. Using the non-LTZ wiring harness, I installed 50w 6 ohm resistors with no luck 2. Using the non-LTZ wiring harness, I disconnected the Morimoto resistors that came on the tail lights and installed 50w 6 ohm resistors with no luck 3. I hacked into the LTZ wiring harness with and without added resistors keeping the Morimoto resistors plugged in with no luck 4. I hacked into the LTZ wiring harness with and without added resistors disconnecting the Morimoto resistors with no luck 5. I disconnected the Morimoto tail lights and installed incandescent bulbs into the non-LTZ harness and still get hyper flash 6. I tried wiring the Morimoto tail lights directly to the trailer hook up and still get the hyper flash 7. I connected the factory LED tail lights using the correct harness and then wired the Mormimoto tail lights to the trailer hook up and the hyper flash stopped 8. I called Morimoto and they were not helpful 9. I called two Chevy dealerships and asked if they could eliminate the error code but they were unwilling to touch it Attempts #5 and #7 lead me to believe there are some electronics in the actual factory LED tail lights that the computer needs to read in order to avoid the hyper flash. I say this because there should be no hyper flash with attempt #5 because I am using a stock set up and attempt #7 eliminates the hyper flash but requires the stock LED tail lights to be hooked up. I realize my issue is self-inflicted due to these lights not be intended for my truck but I love the look of these tail lights and was willing to give it a try. I know Recon sells tail lights that are intended for trucks that came equipped with factory LED tails so someone has been able to get working equipment on this truck but I’m out of ideas. Does anyone have any info that could help? Thank you! Paul
  8. I have a Go Rhino sport bar in transit, I believe I will be purchasing (5) Q Series LED pod lights from Rigid Industries. I'd love to see how others have ran their conductors for power, fuses, disconnects, and cab / interior switch setups. Any and all pictures , and information are greatly appreciated. Youtube and forum searches have been mostly a bust. Interested in what lights you all are running? 2016 Silverado Z71 LT Crew Cab
  9. 2007 suburban k2500. 6.0/4l80e. I have a click when cranked situation no start. Also, power locks cycle every time it’s cranked. If you hold the key in the crank position it’ll click every few seconds. With the key in the on position I’ve had multiple windows roll themselves down, locks cycle, all kinds of dash lights. So far I have replaced the battery, the starter, main power wire from fuse block to battery, starter power wire to battery, I’ve cut the end off the alternator power to battery cable and terminated all these wires with a different style battery clamp. I am bypassing the 175 amp megafuse. All 2 gauge wire. To my knowledge the oem battery cables are shit so I opted to make my own. On the ground side I’ve replaced the chassis ground to battery wire, the engine to battery ground wire, and I’ve added an engine to body ground wire to rule out the. Braided ground strap on the back of the drivers side cylinder head. No blown fuses, I’ve switched the starter relay with another of the same size, and nothing has changed this trucks condition. I’ve tried tilting the steering wheel to see if that would let the truck start and it didn’t. I’m waiting on an ignition switch to come to oreillys this evening. I’m completely lost. I removed the under hood fuse block and inspected it and didn’t see any corrosion on any connectors. I’ve heard there’s some intergrated relay in the fuse block that could be the issue but I have no idea. I just bought this truck knowing it needed a battery and brakes, drove it off a trailer and parked it and went to move it 3 days ago and got this by surprise.
  10. here are some picture and videos of how i installed my upfitter aux switches to my 2017 silverado Texas edition truck which DID NOT com with them nor does it have the relays fuses or switch wires in the harness. keep in mind the switches are GROUND or NEGATIVE switching. which means they DO NOT HAVE 12v ON THEM. DO NOT PUT 12V ON THE WIRES YOUR ABOUT TO INSTALL. i had to get a new connector from a crashed truck in a junk yard which i then pulled 4 of the pins and wires out of to install into my trucks harness plug for the upfitter switch. once i did that it was just a simple act of making a short extension wire from those 4 wires coming from the harness plug to go to the driver kick panel where im going to locate the relays for the devises i want to control. you will see the harness plug and wires where i put them. and you will see the JST plug i used to connect the 4 wires to the extension wire to run to my relays. will also upload videos soon.
  11. I would like to install a custom USB hub for my truck. I am fixing this thing up for camping trips and we will definitely be needing some juice. Can anyone direct me to some products? Truck: 1992 GMC 1500
  12. I have a 2015 Silverado 1500 LT CC. I recently purchased tow mirrors and installed them. The tow mirrors I purchased came with the wiring for the lighting if your truck didn’t come with mirror lighting. Theres four wires I need to splice in somewhere (per mirror) The wiring diagram they gave me was vague and I’m not too sure what all of the lights are: -Signal on the glass (+) -lights (-) -Reversing light (+) -Clearance light (+) I am an avionics guy for airplanes so I’d say I’m ok at wiring. I tried tapping the blinker wire into the BCM but blinker wouldn’t come on. I also read the you really shouldn’t splice into the BCM. Does Anyone have advice for running these wires and where I can tap into ? P.s. I know someone on here sells a harness, but I don’t want to spend extra money if I don’t have to. I already ran the wires in the cab.
  13. While checking for bolt holes for a trailer hitch, i notice under the rear fendor on the drivers side a flat female connector. It was about 2-3 inches wide. Is this some sort of trailer wiring connector and if what is the adapter to fit it to trailer wiring.
  14. In the lighting circuit description I finally found that states it is for a 97 truck, it lists "fender lamps" and I'm wondering which ones that means and if those are only on a C3500 Dually. The list shows: License Lamps Park Lamps Tail Lamps Ashtray Lamp Roof Marker Tail Gate Lamp Panel Lamps Trailer Tail Lamps Front Side Markers Fog Lamp Relay Door Switch Illumination Lamps Fender Lamps Headlight Switch Illumination Lamp. I don't have Roof Markers. I don't think I have Tail Gate Lamp. (assume that is suburban/tahoe) I have the factory trailer pigtail. I don't have a Fog Lamp Relay. I don't know what the Fender Lamps are. I don't think I have them. I can account for all the other stuff on the list.
  15. Looking to put an aftermarket Led Light Bar on the roll bar of my 2016 All Terrain X. Has anyone attempted this yet? I noticed the roll bar is wired from the factory for the GM accessory off road lights. Looking to see if anyone knows what fuse I should tap into and what wire for the fuse, assuming its already wired to a relay. Thoughts??
  16. hey yall, been a while. I have a message that's been coming up in my cluster display saying service trailer brakes... uh no trailer on atm . so I pulled the trailer plug out, inspected for corroision, none found, check for shorts in the 7 pin connector itself no problems, I have continuity through all the 7 pins and the associated 4 pins below, only fault in the trailer brake module was for voltage to low from by battery being dead this morning. im thinking the battery died because of the trailer brake faults. it usually after it rains and then the sun comes out, but this morning was the first time my battery died, anyone else have a problem like this. anyone have a good wiring diagram for modules to the plug on the bumper?
  17. I plan to direct wire a 12v power outlet to truck bed (2018 Colorado). I have done this with a passenger car but uncertain how to connect with this battery configuration. Any suggestions?
  18. Hey everyone, I'm on the hunt for a dash harness for a 2014+ Silverado or Sierra. If you have one reasonably priced please let me know. Thanks!
  19. I'm looking for examples/photos of accessory wiring in the engine bay. where did you put your relays & fuse blocks for accessories such as lighting
  20. Does anyone know how to hook up the 12v constant power to the run lights in my trailer? They definitely work on our dodge 3500, but on my 2014 Sierra 1500 they don't. My only assumption is its not hooked up from the factory. Is it as simple as the older model GM trucks? Hook up a wire to the post by the fuse box and plug in a fuse for that location? Cheers
  21. Good morning. I am needing help asap. I have an 89 K5 Blazer that I cannot get running. History: First bought after some one spun a rod completely through the oil pan. I know the motor was bad, so I wasnt worried too much about tearing it up. I tried to start to see if everything else worked. i.e. starter, alternator, fuel pump, etc. Everything worked. So I immediately shut her down. I bought a replacement 350 from a running 94 Chevy 4x4 Pickup I put all wiring back in place as they were before. Replaced all fuses, spark plugs/wiring, rotor cap and button, etc. Now I have no headlights, slow turn over, wont start. I have removed the fuel line from motor, turned the key and NO GAS. I checked the fuel pump relay and its good, checked the fuse panel and its good. I know it is a long shot but wth do I look for? I am a mom and this is my only vehicle and need to get it running asap. By the way, At some point some dipstick turned it into a push start. Turn the key then push the button. I need help asap
  22. I bought a 2005 GMC Sierra 2500hd 5 months ago. I had a brake light (right side only) issue on my holiday trailer, had the 7 pin changed on the truck to no avail as that is what the mechanic said was the problem. The mechanic then told me to change the flasher under the dash (10 pin) so I did that and that fixed the trailer issue. Just last week, when I push the brakes on the truck, the signal lights on the mirrors both go at the same time on half solid but do not blink, both signal lights on the dash dimly light up, the third light on the truck signals, and the signal, brake lights and reverse lights outside go nuts. I just noticed today it only does this when the head lights are on, when they are off everything works as it should. Any help would be greatly appreciated.
  23. I'm trying to wire up the towing harness for my 2014 Chevy Express. It didn't come with the factory tow package. I've found a wiring harness that has the wiring for the trailer. It is terminated with a Delphi PA6-GB20 GF10 terminal. The problem that I'm having is finding the harness that plugs into this, I'd much rather plug into a factory harness than start splicing into the wiring. No one has been able to help me though. I've been to several auto parts stores, looking online, and a few dealers parts departments trying to find the correct harness. No one has seen or heard of this. Searching online by this part #, I've found a lot of Delphi connectors, not one of which look the same as this. Can anyone point me in the right direction? I'm stumped here.... 2014 Chevy Express 3500 LT, extended, 6.0
  24. 2002 chevy silverado 2500hd 6.0 truck randomly dies no rough idle, no lights, no error codes. Truck won't start up right after it dies but if I let it sit it will start up fine anyone else have similar issues or have any ideas and what it could be?
  25. I drive 2000 Chev Silverado 4wd ext cab LS edition. I bought 1999 GMC Sierra SLT with power and heated memory seats and the centre console.. I'm looking to swap all this over.. am I going to run into wiring issues or what? I've got the whole Harness that goes into the doors and into the seats. Will I need to swap over the SDM module and other harness that routes with this? It looks the same as what I have in my truck but I'm not sure. Please any help and guideance would be appreciated!!
