Any way we can get the mirror work lights to stay on while the truck is in drive? I didn't realize the truck had to be in park for them to work but they it makes sense from a DOT stand point.

I would just like to know how to have the mirrors open up when you start the car.

This mod keeps the fogs on anytime the park lamps and/or headlamps(hi and lo beam) are on.    If you just want to keep them on with hi beams connect a diode  from pin 18 (bn/vt) to 10 (bn/wh

Brown connector on BCM - Jumper  pin 10 Brn/wht to pin 22 Blue.    Fogs will come on with park/head lamps now. No need for diode.

I would at least like for the mirror lights to turn on with the cargo, bed, and reverse lights along with fogs when unlocking...to light up the parking lot lol. Iam sure it’s possible as I had my cargo lights wired up with the reverse lights and they would come on after pressing unlock on remote on my 17. I just need to find the rest of the sheets that the OP attached to figure out whwre to slip in the diodes

Found the info. So far I was thinking of putting a diode from pin 18 module X2 (gray wire) to pin 4 module X7 (gray/blue wire) and this way have the cargo lamps come on with the bed lamps and have extra light when unlocking vehicle at night or when loading up the truck bed at night. 

 

What do you guys think? I would like to include the mirror perimeter lights but I couldn't find them on any of the modules...perhaps I overlooked it.

I need to try that. Really wish these trucks came with led reverse lights, there is no output from the stock bulbs.

Hopefully someone finds something with the mirror lights.

Just placed order for my diodes on ebay emoji4.png

Had this mod on my 17 and loved it.

 

Which ones should we bridge to make the cargo lights come on with reverse lights? I had that one and it was nice to unlock from far away and see all lights come on and shine through the parking lot!

Did you ever figure out how to do this? Do you have a link for the diodes? 

 

I'd like to get my fogs to stay on with high beams as well, if anyone has more info on how to do that I'd appreciate it

Gave it a go earlier today and inserted the diode. The brown connector comes off easily but the wires are so close together that the I couldn’t get the diode to work. The fogs were not lighting up with the drls. I’ll probably have to order the wire jumper that the OP requested or maybe give it a second try later. I know i struggled a bit with my 17 but not this much lol

Super easy to do with the jumper wires from above. When inserting into slots 10 and 22 make sure that you try from all for corners of slot and pic the where it fits most snug.

Thanks for sharing pics!

 

So this makes the fog lights come on with the running lights? Then they stay on with high beans on?

After having it for a few days. I discovered it goes on with park lamps which I misunderstood for DRLS...so basically fogs will kick in when your low/high beams are on at night or if you turn the knob into park lamps. I tried using pin 7 instead of 22 to see if fogs would come on with DRLS but I couldnt get them to work. So I went back to pin 10 and 22. 

Still want to try the others this weekend and report back If I have other successful turnouts.

Would love to see a harness that keeps these on with the high beams

This mod will keep your fogs on  with the highs beams as well, and even when the Intelllibeams kick in into high on their own too :)

      MPG at 600 miles

      By Chuck FB · Posted

      I would have to read back to get a better picture in my mind of some of the other comments and what they were using for a driving scenario they based the fuel mileage off of. That is why the fuel mileage conversation is extremely difficult to make fair comparisons from. If I was to be living in town and only driving around town, light to light and some longer stretches that doesn't have a light every block, and the usual stop at a grocery store and the bank and so on and so forth, my fuel mileage even during the summer time would be so bad with my truck I don't even want to know how bad it would be !. Then add in winter time and idling to warm it up to clear the windows and driving through snowy streets etc, large heavy trucks with gas engines have NEVER been worth crap for fuel mileage and why some little pot licker of a car with wheelbarrow tires and a 1300 cc four cylinder non turbo engine was the ticket to using a mere fraction of the fuel over a full size pickup.    By the way my truck has the 34" tires as its a HC but not the BFG KO3 tires ( that was an option for my truck but the sales guy couldn't figure out what the tires actually were so that never got on the order until it was too late to change the truck order ). So what fuel mileage your getting actually sounds good for "town driving" and with my truck when I go to town the fuel mileage keeps increasing as I get closer to town because it takes quite a while to get the driveline oils warmed up ( and why it always shows better fuel mileage on the return trip from town because its already warmed up ) but once I am in town that fuel mileage average just keeps dropping the more I mess around town and then has to recover back to something reasonable again by the time I get home for an over all average.    I'd be curious what your sticker says for the factory weight of your truck, mine is close around that 7700 lb due to the options it has. But anyway the long and short is, vehicle weight, higher rolling resistance heavy tires and a hefty driveline and a relatively large gas engine make for crap fuel mileage in stop and go scenarios, all one can do is drive it easy off the line at each stop and as my dad had said over the years, drive like a raw egg is under your foot and that's the best one can do. Years back with a carbed engine and if the carb was getting a bit out of tune etc as would the ignition system, the fuel mileage on pickups with larger engines was just awful compared to what your getting. We pay the fuel price penalty for driving HD trucks over some little vehicle, that is the reality.

      Slate Electric Truck

      We had two Toyota’s with that engine in the mid 80s. We had 50 gallon fuel tanks, a toolbox full of tools, an air compressor and assorted parts for our equipment. We beat those up and down pipeline ROWs until we started buying diesel trucks. Then they became parts runners and first vehicles for our teenagers first cars. Our shop Forman wrecked them both two years apart when we hired him out of high school as an apprentice. Good thing he’s an excellent mechanic. It took awhile before he could be called a good driver.

      Bent valve in 2025 GMC Canyon Denali - Requires engine swap at 14K miles

      By William Aldrich · Posted

      I have a 2025 GMC Canyon Denali.   On a trip recently the engine failed.  The dealership diagnosed a bent valve and says there is a service bulletin that indicates to 'relace the engine'.  The truck only has about 14K miles and is under warranty.   The failure occurred 5/11/2026.   So far I have worked with GM Customer Assistance and Roadside Assistance.  Evidently no engines are available and nobody will offer a date when a new one will be.   Coming up on two months with no repair or timeline and no loaner from the dealership.   GMC Customer Assistance is 'ghosting' me and keeps closing the cases I've opened with no resolution.   Hoping someone can help me on how to escalate this issue.
