Hey guys,

Sorry if this is a redundant question, but I couldn’t find the answer from other threads. I’m wanting to install pod lights on my utility trailer to use as reverse lights. I’ve have a 2021 GMC AT4 1500 and don’t want the trailer pods come on every time the vehicle is in reverse. My plan was to use one of the OEM upfitter switches to activate the trailer reverse lights. I was thinking of cutting or depinning the vehicle’s 7 pin reverse wire and connect a 10ga wire from the truck’s reverse 7 pin to the upfitter switch. I could then use the switch as a trigger for a relay to activate the trailers reverse lights.
 

My uncertainty is if I do cut or depin the truck’s 7pin reverse wire and connect it to the powered upfitter switch, will it cause problems with the advance trailering system? I know these trucks use the resistance from the trailer to activate the 7pin, but not sure if modifying the reverse pin will cause faults or errors.
 

Thanks for any information anyone can share. I’m sure someone has already tried this.

The 7 pin already had a reverse light circuit in it... you say "don’t want the trailer pods come on every time the vehicle is in reverse." Why not? Seems like you are adding a bunch of trouble just to keep the lights off some of the time.

Just run a switched power with ground to from the truck to a two pin connector on the trailer for the lights. You start hacking the trailer wiring on the truck you could run into a whole bunch of issues since it runs through the BCM and people have issues with older trailers as it is.

      I'm tangentially aware of what Harley used to be, back in my riding days, although I was into Italian sport bikes. Ducati seems to have gone the other way; still very expensive, but they've made a large subset of their bikes a lot more reliable and accessible, and they've diversified their lineup to include other riding sports too. IMO, a good example of where greed and growth might have also been beneficial to the consumer.   Although GM is charging a relative premium for its most popular pickups, I find that there are some excellent value propositions in its lineup as well.   The Colorado still strikes me as the most attractive midsize on the market, and also the most reasonably priced given capability and features. There's a part of me that wishes I would have bought one instead of my Silverado.   The Equinox ...I must be getting old. The ICE equinox is a great design IMO. Probably because it reminds me visually of an actual SUV aka an S Blazer. Underneath it's nothing even remotely close, but it LOOKS good. It's got all the modern features plus some at a very reasonable price. If I had to run out and buy myself a daily commuter to do everything except tow, an Equinox would be on my list.   It does bug me that mid-tier 1500's reach into the 50-60k range, and Tahoes and Burbs are even more expensive. Less than 10 years ago, dealers were sitting on rows of Tahoe LS and LT's for low 40's. You could even still find Tahoes with a front bench, still!

      Gas Prices

      Big oil is raking in billions from the Iran war. Can it avoid Trump’s fury?   Remember I said Big Oil is 'Vertically Integrated"?   Even as they no longer own the majority of the "Pump" they still own the "Well". Crude price upward pressure does not translate into that same pressure on production. Pumping cost remain unaffected and the gap is pure profit. Even after subtraction of a minor, comparatively, lower amount from supposed, but not always, realized refining volume. Consumers hate war, Big Oil, not so much.

      2027 GMC Sierra: Official Discussion

      We live in a world where the average person expects more. People say wages and our needs are farther apart. My first new home had 3 bedrooms and one bedroom. My first car and truck had what would be considered a stripped or work vehicle. In my neighborhood back then there were more homes like that and cars too. Middle managers and second home buyers worked their way up to the fancy houses and cars. Car loans were 3 years. GM had different models of cars for different income levels. The cars were pretty much the same size if you wanted a big vehicle. The nameplate designated the opulence. Chevy, Pontiac, Buick, Oldsmobile and Cadillac.  To be fair some of the cost is government mandated. We can’t blame them for giving us what people will pay for. Careful advertising steering people towards more profitable SUVs and trucks. As I learned recently a minivan is a cheaper more efficient form of transportation. Certainly easier to live with. Somebody realized the profit margin wasn’t as big and gave it a soccer mom label. So it lost its coolness. They’re making it the masses are buying it. You hit your hand with a hammer you can’t blame the hammer.

      Electrical /Immobilizer Data- Battery Voltage (V) Test malfunction

      By Aussie2500HD · Posted

      Hi All, I’m In need of advice regarding a scan result on my 2023 Silverado HD.  The Sensor Supply voltage relay states ON But…. the following 3 tests show Malfunction. Sensor supply voltage relay control circuit HIGH voltage Test status- Malfunction Sensor supply voltage relay control circuit LOW voltage Test status- Malfunction Sensor supply voltage relay control circuit OPEN test status - Malfunction. No DTC codes are stored. No DIC Lights. Remote Key Fob has been giving a few issues, namely Vehicle will not respond to an Open/Lock command from the key fob. New batteries installed to FOB made no difference, plus on one occasion recently the vehicle unlocked using the Fob, the vehicle started normally via the push button, then a random warning came up on the DIC stating the Remote Key was not found, all this while the key was located next to the central cup holders. Does anyone have any input or advice regarding this scenario? TIA
