Has anyone installed auxiliary reverse lights on their 19 yet? I usually wire some pods to the trailer wiring but I would like to utilize the cargo lamp button, not sure if this is possible so any input is greatly appreciated.

Rigid Ignites finally wired.

I'm not sure if this will work for the T1, but a clean look is mounting Rigid Ignite Back-Up Lights in the rear bumper step. I did this on my 2016. If they don't fit inside the step, maybe they'll fit

All I will say is it would be best if you set it off a relay to a seperate power. You can wire up a relay or buy a rewired on or even buy a relay power harness. But so many wires and circuits are monitored by the bcm. And throw soft codes.

LEDS draw such low amps, and I yes the BCM is finicky , but i wired back up LEDS and additional bed lighting, into the respective lamps direct... No issues...

I'm not 100% sure there is a problem on that circuit but my dome light wire I tapped into for floor mat lights and there is a soft code in the record. Also in my report was subwoofer open and light sensor high voltage.
These are soft codes they do not set of the dash light. But when all the codes are pulled you can see it listed.

Agreed there maybe hidden soft codes, but they don't affect vehicle operation...

You are absolutely right. I didn't even know I had them till I read the 2 page report of soft codes.

I did what you are describing on my 2015. Used the cargo light circuit to power two KC Cyclone led lights. No issues with it, I'm very happy with the results. If it worked on the K2, why wouldn't it work on a T1?

Thanks guys, I will most likely be adding rigid ignite diffused reverse lights under the rear bumper. I believe they draw under 1 amp.

Does anyone know the wire color of the 7 pin reverse/auxillary? It appears green with white stripe, black and a red with green stripe come from the center of the rear on harness.

Reverse on my truck is green with white tracer being a Z85 trailering package. Unfortunately this was not a good power source for auxiliary lighting because the truck has to sense(electrically) a trailer in tow to work. Next step I tied into the blue positive / black negative on the cargo lamps. This would allow the aux lights to flash 3 times then shut off all cargo lamps. My little project is much harder on this new truck then the last ones I have had.

If you are wiring in additional reverse lamps , pull the talilamp assembly and tie into the reverse feed there.  Thats what I did. No issues..

Share the details, I was intending to have a switch in factory location...obviously out of luck so far. I removed tails to tie into cargo but ran out of time. What color is reverse on the tails? TIA

Please comment on how those work.  Are they pretty bright?  Do they light up the driveway (about 20 feet across) when you’re backing up?  Any other pros or cons in the choice of lamp?  Thanks.

I don't recall the wire color. Use a multi meter / test prob while someone places truck in reverse...

They actually suck... I wanted the slim line for a clean install, but they don't put out the light... I'm going to eventually replace with the 2" flush mount cubes in the bumper... Just haven't gotten around to it yet...  Something like these.  https://www.amazon.com/Rough-Country-Square-Lights-70803BLKDRLA/dp/B07KYTX6MS   Clear not amber like listed

      2026 6.6 L5P oil cooler leaking oil at 4,000 miles

      By Brendan C · Posted

      New to diesel trucks. I happened to find my oil cooler leaking oil externally with only 4,000 miles on the truck. I didn’t realize this was an issue until I started researching it. Dealer is going to replace it under warranty but I’m wondering if there’s anything GM is working on to fix this issue. I’ve heard the oil filter used is the same as they use on their V6 motors and that’s what is causing the problems. Should I switch to a bigger filter or keep using the OEM recommended?

      Seems to be Missing a lot of Updates

      By Vu1can · Posted

      So, GMCustomerService:  Judging by the Update History pictured above, is this truck missing any updates that it actually needs. If it's just for the infotainment system, the radio is working fine and no trouble with SeriusXM. and Android Auto is working fine wirelessly with my phone. Some months ago, an update notice was sent to my truck. I approved the update and it finished saying that the update was successful, but it seems that whatever that update was, it didn't actually get installed - at least not if I'm to go by the Update History shown above.   So, again, are there any updates that this truck really should have? I've checked with my dealer but they're reluctant or commit to anything and if I want them to check, they require a $200.00 fee just to check it out and then I'd have to pay for the actual update(s).    Ignorance is bliss, and if none of the updates goes to fixing any mechanical discrepancies, I'll just leave things as is.

      Electrical Problem - solved

      By CNH-320 · Posted

      Hey everyone, I recently had an issue with my 07 2500HD GMT900. My DRL’s stay on at all times. Right front turn and right mirror turn signal indicator stay on solid at all times. By “at all times” I mean the only way to make them go off is disconnecting the battery. I tore the headlight assemblies out, tried disconnecting the harnesses to eliminate bad wiring at the harness, I unplugged the headlight switch, no change and the mirror turn signal still stayed on. My first thoughts were : Bad bulb and/or socket somewhere, under hood fuse panel bad, bcm bad, tail light or trailer wiring problem, or some random short to power in the harness.  Possibly a bad ground but unlikely. I had a big clue in the fuse panel, it had a burnt smell. I started pulling every fuse that had to do with DRL or right turn/park lamp. Nothing made the right directional turn off but pulling the DRL2 fuse made the DRL’s go out.  After studying wiring diagrams, I found that both problems had that fuse panel in common, the bcm also controls both problems but knowing the fuse panel had a burnt smell I removed and disassembled the fuse panel and found a little corrosion on the printed circuit board.  I ordered a new fuse panel from Amazon for like $260. When it arrived I installed it, and put everything back together, the problem was fixed. I figured the fuse panel needed to be replaced anyway so that was a logical place to start. Hopefully this story helps someone in the future. Regretfully I didn’t scan for codes before I did everything.

      That stinks. I’m sitting on the side of the road right now with the same issue. Never had an issue before taking it in for the ground strap recall. Now I’m outside of warranty and they’ll probably want $200 just to diagnose what they already “fixed”.
