I just went directly off the cigarette lighter wires. Constant positive (with tapped inline fuse) and negative right below the upfitter switch location. Installed my relay above the little compartment that is right next to cigarette lighter.

I have just successfully fully integrated my AUX switches OEM style. My fuse block did not come with the relays or fuses, nor did it have connectors for them. I had to purchase a few new things.

Here are some pictures of the modified buttons. I had to remove all the black and white, then respray the white because you couldn't see the icon in the daylight. I am pretty happy with the way they

For most of you you don't want to put holes in your new truck. I have a solution for you. If you haven't seen it already.

 

On some of these trucks (ie work models) you can get upfitter switches that go where your traction control and cargo light switches go.

 

Trucks with only "traction control" & "cargo lights" can use this. ( if your truck has bed lights or a park assist it won't work.)

 

Looks like this d853e64d9587972cc5b975e6404df679.jpgthe empty switch is just a blank. (Does nothing)

This switches are ground controlling. So you can hook them up to the negative of a relay. Mine are on the way and I'll take/show how it works.

 

another option if you have a console is this

Ok so I have a 2014 Silverado 1500 WT2, got the 4 aux bottoms as well now. I've heard the Fleet tucks(which mine was) can use these.

 

Can anyone give me direction of how to hook light bars up to these in the Fleets?

So here is a question. I just bought one of those aftermarket park assist, I changed the rear bumper out to body color and got one that had the holes already so I figured why not. Anyways I am going to buy the switch bank with the park assist, TC, and Cargo lights. My question is this, I have no idea about that kinda wiring is installed in the truck at the moment but either way is the latching relay part of the switch bank for this switch or do I need to buy one separate? I plan on just intercepting the speaker itself for the beeping and not then entire unit.

I'm seeing a lot of guys that want to add these switches are having some trouble.

 

To the guys with ONLY the dome light and traction control switches from the factory be interested in my building a kit for them that they only have to install it into there trucks?

So I bought the 7 switch bank (previously had only Traction Control and Bed Light switches. I also bought one of the wires that goes in the connector.

 

I installed that wire on one of the AUX pins and verified that I have continuity between it and Pin 14 (GND), when the switch is turned on.

 

HOWEVER, I DO NOT have continuity between Pin 14 (GND) and the frame of the truck!! How am I ever going to energize the coil of a relay if the GND isn't truly the trucks ground?!

 

Any thoughts? Does anyone know where that ground on Pin 14 is sourced from?

It's probably a common ground for the ECM. Alot of these switches are originally ECM controlled. They do not carry high amperage. Just milliamps.

 

Also the coil side of a relay uses only milliamps to activate. Takes almost nothing to turn them on.

 

Maybe the way you're testing is slightly wrong. I would try wiring up a relay and see if it will actuate the relay. And if it works move one to wiring it up permanently.

I ending up figuring it out.

1) the door hinge is NOT a good ground.

2) after testing the relay I was using (brand new), ends up it had a direct short from power side to coil side. It fried my Aux 1 switch unfortunately.

Replaced the relay with a bench tested relay and moved over to Aux 2 and all was good!

So if everybody is wondering on how to install these auxiliary switches (GM Oem P# 23145158) without the GM upfitter diagram. I purchased the Bussmann 15303 - 5 it is a weather tight fused and relay box, took the wiring diagram that GM up fitter provides and did my own diagram. I also purchased the Pre- crimp wires to go into the back of the harness (GM OEM P#13575783). Made it much easier than trying to figure out what size connector it was. Purchased all parts needed from Delcity.com. Wire I purchased at my local Automotive Store 12 gauge for 20 amp, 14 gauge for 15 amp, 18 gauge from relay (pin 86) to switches. Works Fanstastic.

I've read this thread twice now and one thing that is not completely clear to me is the operation of the 4 aux switches. In your diagram you have both the power for the coils and the contacts just coming off your battery(constant +12v through the 50A breaker). With it setup like this can you push the button and activate the relays with the truck off and key out and therefore have to manually shut the switch off everytime?

 

Obviously you could wire switched power(RPO) to the coils of the relays to have it switch off when the truck is turned off(which I don't think is an option with the particular fuse/relay block you went with, since it seems to share one rail).

 

 

IF the switches turn off with the truck even with constant power to the relays do the switches retain their position? (ie. if your lightbar is on when you turn the truck off will it be on the next time you start the truck or will you have to press the switch every time you get in?)

How do you connect your wiring harness to the garage door openers to work as the switch for the LED bar?

 

 

hey... you know what that on/off button is for?.. i have my led wired and i have it set to off.. but i'm still able to turn it on/off by the homelink buttons....

 

just curious to what that should be set on..

sorry maybe wrong person to ask Akkrezz.... anyone know what the on/off button does on the wireless harness?

 

 

i guess its just an on/off .. for manual.. ?..

 

 

edit : also i just emailed I-offroad about the wiring harness... my light came on in the parking garage... not sure if its on the same frequency as maybe someone's remote to unlock their car... but i couldn't turn it off via the homelink.. i had to use the remote... just fyi... i pulled the fuse so i can at least make it home today... and will try and reprogram the homelink back to factory as not to use it, but use the remote the harness came with.. keep ya'll posted.

Just a couple be pictures of non oem install. Could have spent way more $$$ and make it look like it should be there. But if it works it works. 597e89f67588aaeae84fd3e563a88b87.jpg4e5b8601d6eb9a9fa59fc54cbace30a0.jpg86c9344d9906216ce1a1429149554b49.jpg59d77fa7cff4627f9f4802c4877a1b7e.jpgf96f2ee0e1b687c1f4a543c8a385de48.jpg45631a6d8b6289355f32443a91418928.jpg18790385374367c828cee9ed9ec8d6e5.jpgefcc34e77b29cc05fb87ffe239551817.jpgc64b2782081eaf4eaf6ef5230269ab61.jpg

      Roll up bed cover experiences

      I have a Retrax pro that I first had on my 2020 chevy and transferred it to my current GMC.  It stays in the garage most of the time, so hard for me to judge it's long term weather resistance.  It still works perfectly, been very durable.  It doesn't see oil patch usage, but it's not a mall queen.  It keeps most things mostly dry (small leaks) and the security of it is enough to slow someone down but not keep them out for long.  I would buy one again, it works for me.

      Thanks to the convenience of Amazon, I was able to get a few things done to the truck today.  I installed Carquest Premium oil and air filters with five quarts of Mobil1 High Mileage 10-30 along with a quart of Pennzoil Platinum 5w-30 I already had.  The latch for the flip up center console lid was broken so I replaced it along with the power mirror switch.  I found my push retainer assortment this morning and reattached the plastic under the bumper and it was only held on with a few screws and retainers.  Then I programmed a new remote keyless entry fob so I can lock my dog in the truck when I take her out with me (I've got to keep the air going for her since it's been in the 100s).  Finally, I ordered some LED interior bulbs and replaced the reading lamps.  The front lights are working fine while one of the back lights only works intermittently and the other not at all.   While under the truck, I found the source of at least one of the noises: the sway bar links need replacing.  I ordered a set of Suspension Dudes links with Code Red bushings.  Never heard of them, but they're made in the USA and have decent reviews.  While making yet another Amazon order, I went ahead and added a set of front tow hooks.  I went with red, since that's the color of the sway bar link and bushings and it should look decent enough on a black and chrome truck.  Speaking of which, it doesn't bug me much, but the passenger side mirror has a chrome cap while the driver side doesn't, so eventually I'll make them match one way or another.  Oh, and I ordered a $20 TPMS reset tool.  No idea if it will do anything for my sensors but it was cheap and will work for the Ford Transit Connect as well.     For tradition's sake, I ordered a new oil change wrench.  I kept the Snap-On 9/16"x15mm GM wrench I bought when I was 18 in the 2006 GMC from the time I bought that truck until the truck was lost.  While I was tempted, there's no need to spend $80 for a new SO wrench, or even $50 with shipping for a used one on Ebay.  I just bought a Duratech 15mm extra-long ratcheting wrench to do the job as needed.  It works, and if I like that wrench enough, I'll buy the set.

      Multigate electrical problem

      By Another JR · Posted

      The recall is for exactly this issue - those drain holes combined with the limited environmental capability of the tailgate electronics card inside the tailgate were a problem. The “safety issue” was the potential for the tailgate to spontaneously open, but all kinds of tailgate misbehavior can occur from water contamination of that control card.    There is no real fix yet. The initial recall just disabled the tailgate. Later, when parts became available, they would replace bad parts with new parts of the same bad design. My dealer is going nuts because the few times I let them get their hands on my truck, my tailgate is off due to a slide-in camper installation. They really want to cut my tailgate wires, but I won’t give them the chance. I will let them get their dirty hands on it when a real fix (redesign) is available.  My tailgate, which works just fine with sealant plugging the drain holes, will remain safe in a dry storage crate until then.

      Yes your absolutely right, I been looking at the 4 inch BDS one and it acutely states you can use the stock 20’s just not the 17’s or 18’s, I also didn’t realize that with my 275/60r20 stock wheels I’m already running 33 inch diameter wheel setup lol so I can just run my stock wheels and tires atleast to start.

      I would expect that to be lift-kit dependent.  If the kit has interference issues w stock wheels, then the kit/manufacturer should indicate that somewhere.
