Have you seen the Michael J Fox Edition Sierra/Silverado rolling down the road? Looks like the Toyota from Back to the Future. Anyway there is a really cool headlight switch with the option for Off-Ro

For you guys with 2014/2015 or anyone else that this doesn’t work for (due to BCMs not being programmed to output these triggers), please be patient with us. We have an alternate method that allows

Ok folks, for anyone wanting this headlight switch harness, I have them ready made, and ready to ship.   $35 shipped anywhere in the US.   They are built with the same specs as shown in the vide

That crimp tool will work, you might need to finesse the edges of the crimp to make them conform to the cavity but they’ll get it done. Bummer about the color but I’m sure you’ll find a buyer. Also I’m pretty sure @pgamboa can send you a harness cheaper and faster than buying the tool, wire, tape and terminals...etc Also I haven’t seen a Silverado or Sierra with anything but JST connectors, the written instructions are for a Canyon/Colorado.

@TinkeringFox I've seen the same thing with the connectors on the suv plaform...all JST at the BCM.

I ordered the old blue # 23317218 online from gmpartsoutlet.net for $42.47 with shipping. Works perfectly!!

I'd really like to thank TinkeringFox for the awesome video and information. Have everything installed and functioning beautifully. 36,000 lumens on that light bar. I had purchased the OEM Sierra's RED switch by jumping the gun , but I actually think the Blue & Red match the instruments cluster pretty well. I'll take some pictures of the buttons illuminated later and where I installed my relay. I had a slightly different install.

I hit a problem with my 2019 Silverado 2500. I had my lightbar installed and running prior to soldering in Pgamboas harness.

I plugged in his harness to the appropriate plugs, changed the OEM light switch, soldered it to the trigger wire, I even used the same ground and power locations, bolted the relay to the same spot too. But unfortunately the light bar doesn’t turn on with the factory switch. 

Do I have to get the ECM flashed or is it just not possible on my truck? JST and Delphi plugs just like in tinkeringfoxs video. 

Everything seems very straightforward and i’m 99% positive i’m in the correct pin locations, orientated correctly and pushed in far enough. I bought and replaced the relay that didn’t change anything, fuse is good going to the light bar and my ground location is good. 

Any help would be greatly appreciated.

Check to see if you have power coming out of the switch. Then ohm the wires out. It was my luck, there was a break in my yellow wire somewhere. I replaced tha wire, all good.

In my case, yes, it was just a broken wire. Mine is a 14, so it wasnt able to be wired to my bcm. 

 

I would still take a test light and see if you have power coming out of the switch. Also, dont you have to do a long press of the button?

I’ve held it for 5-10 seconds at a time and not a thing. No click from the relay no lights on the dash or from the lightbar. Will have to go find a meter and check this out thank you.

A simple test light will check to see if you are even getting the signal out of the switch.

      Tire psi

      By jgaudet99 · Posted

      I tried before I updated the scan tool just incase an update messed it up, but it never worked so I updated the scan tool and it still didn't work.   Only difference is I click on Sierra not Chevrolet cause I have a Sierra.   If I click on 2026-2024 I didn't have any option to change placard, when I click on 2023 it does give me the option but when I try to do it,.it says vehicle not supported!   I have my region or market or whatever it is set to America I think, is that what yours is set to?

      Its just that it worked on 2024 trucks on this forum and my 2025 model truck, unless GM did something since that point to screw up access or Autel has a bad update. I haven't had need to use my tool since last year when I did the changes to the placard pressure settings and since then I updated the software on my Autel but have not plugged into the OBD so hard to say if I would get a surprise as well.    All I know last year when I bought the Autel I was warned to be sure to update it before I tried using the unit as they said who knows how long ago unit itself was actually manufactured as the software could be way out of date.

      And so you had gone through the process of registering and updating the tool and so on ?. All I can say is that on the front page as the tool fires up you go to advanced mode, then vehicle model comes up and you choose Silverado ( not the DRW or EV  since your a single rear wheel ) , then I think its choice 2 which is 07/2021 - 12/2026 ( 433mhz 13542523 ) as that is the series of tpms sensors and then go down to choice 5 which is tire type/pressure selection. Hit yes and it says to connect to OBD port and turn ignition on.    Having said this, I updated the software in my tool lately and these year range choices look different from the past due to them doing some updates it would appear and I have not connected up to the OBD port since last year so hopefully I am not in for a surprise with them screwing up the software and that it won't work on my truck anymore either.    So my question is, when you plugged into the OBD and started your truck it had that message on the Autel screen "vehicle not supported" ?. That does seem odd as tire shops would be pissed right off if hey can't use their tool on the model year after mine that in theory is supposed to be much the same truck ... unless GM did some change in the computer system to block certain things from access.

      Understanding and using modern scan tools is its own body of knowledge. I had little hope that would work...programming access to the BCM is probably required and that is not easy for us consumers. Expensive scan tool, GM programming subscription, online authentication, etc.   It also may be a matter of finding the right dealer to program it for you. Flashing a modern BCM might be a little too advanced for most tire shops.

      AUX switch install

      By SwitchBladeSierra · Posted

      Update for anyone following:    Installed everything as shown in diagram. Opted for 8 AWG from Battery Positive to a 50A resettable inline breaker. 8 AWG is tied into to 2x 12 AWG wires feeding a 6 way fuse bus in parallel (manufacturer’s design of what I purchased).    4 of the 6 fuses available for circuits are tied to terminal 30 of each relay. I tied a jumper from one of my spare circuits off the bus to terminal 86 of each relay. The trigger, terminal 85, was pulled from my interior by way of T-Taps from the X61A-X5 pins 10, 11, 17 and 23. This was the hardest part of the job. Even with the X61A unbolted and the X5 removed - there was VERY little wiggle room.  I added back up lights that I want to come on with my cargo lamp - but when I would check continuity between S48A-X1 pin 18 to its respective landing point on the X61A-X5 it triggers the factory relay… Instead I opted for a add-a-fuse on the passenger interior fuse panel (fuse location 10 - cargo lamp) and ran it through the boot on the driver side to my load. Did this to avoid introducing any electrical gremlins.   Note: Please check for continuity between the S48A-X1 and the X61A-X5. In my case wire colours were not the same as other’s who have posted. To do a continuity check you need a Multimeter. Completely disassemble the S48A-X1 and remove the brown face plate off the X61A-X5 by way of a flat head screwdriver - this was the only way I could get any results.   The outputs, terminal 87 of the relays, were fed into a junction box and landed at Individual studs and were labelled Aux 1-4.    At this point, all you need to do is run wire to your loads and bring them to ground. I created a negative bus in the engine bay, all my negatives land here.    For anyone having issues with all of your new aux switch lights coming on with the press of one - I noticed this only to be an issue when the battery wasn’t hooked up to my relays? No idea why, but it was quickly corrected by having my system buttoned up and functional.
