I have a question regarding a modification I would like to do on my truck that goes along with this mod. I've been wanting for my cargo lights/ bed LEDs to turn on when you use the fob to unlock the doors. Has anybody tried this or perhaps know how to accomplish this?

This was on the Duramax forum. I believe it is for a GMT 900. But the principles are likely applicable to a K2. Use this information cautiously. ------------------------------------------------------

OK, After struggling thru the schematics and online mods of past models all evening, I figured it out. This is for a Sierra and should be the same for the Silverado. It involves pushing one Diode in

Just did mine. Literally took a couple minutes. Ran mine from the 22 to 10 and love it. Wish it came from the factory with this opition.

 

In that spirit I have 3 to send out as clatla sent me extras. If you hurry I can get them out today as the mail guy didn't come yet. PM me your address please.

Just bought a 5pk of IN4004 off eBay. When they come in I'll only need one. With that said I'll have 4 I'll pay forward.

If anyone wants one of the 4 remaining send me a PM with your shipping info and I'll get one out to you.

Bought a pack of diodes from the source. Did the mod today jumped off the parking lights relay.

 

Works like a charm.

Maybe I missed it while looking through the comments, but would it also work with a short jumper wire or is a diode safer?

 

You need the diode to prevent current from flowing back and turning on the high beams when you activate the fogs.

:thumbs: The diode is acting like a one way valve for current.

 

Steve, just find a Radio Shack or any electronics store and get a diode. There are many diodes that will work, as have been verified by the guys that used them on this thread. They cost literally pennies.

Thanks, makes sense.

Only reason I asked was because I have a short piece of wire from when I programmed a new key fob for my old 98. Plus I was just curious. Wasn't wanting to save money since diodes are very cheap.

Just to confirm, the high beams will flash on then off when you active the fogs while in low beam?

 

Ps check valve (one way valve) :P

I hadn't noticed that...maybe. My setup is the 10-18 jump. Fogs are controlled on-off in the normal way by the button on the headlight control, when either with the low beams on or in daylight with only the DRLs on. If the high beams on commanded, the fogs will turn on, if they were off, then return to off when commanding low beam. If the fogs were on when the high beams were commanded, they will remain on for the high beams and stay on when going back to low beams.

 

I use this configuration because I can tie in a relay to the fogs to run a set of wide driving lights and not have to run a switch to fuss with when I need to shut them down for oncoming traffic. I don't have to run wires thru the firewall either. Very convenient setup.

Question for someone with a GMC that hasn't done this mod yet:

Can you turn on your fog lights in the daytime without turning on your headlights?

 

My foglights will work in the daytime but not turn on the headlights. I have the 10-18 mod.

      Is the 6.2L L87 in a 2026 Sierra 1500 ok?

      By asilverblazer · Posted

      What meaningful corrections were done to fix the "machining errors?"   I bet nothing, because the 6.2 is soon to be obsolete. Why would GM implement any fix let alone an "expensive one?"   Until someone can provide any convincing information that GM did ANYTHING to correct the engines - the 6.2 is no for me.    Which means keeping the 2016 Denali longer until the next generation (6.6?) proves itself.

      If my father took a Sunday off. We did the Sunday drive. Usually stopping at a Geno’s for dinner that we eat in the car. Six of us with my little sister up front. It was always a Buick growing up. In New Jersey you couldn’t get lost. Not like Texas.

      I suppose I am Atlas. It can always be worse, eh?   I had a friend once that rolled one payment into another until he was paying the price of Benz for a 10 year old back marker. Wouldn't be often you start a new payment the month following your old one.

      I still enjoy the drive   Some people fish when they retire; some golf. I drive. We've lived in the same general area now for twenty eight years and I'm still finding at least monthly some sweet quite little road to explore. When I tell the Mrs. I'm heading out for coffee she knows that could be a five hour event. Often she even goes along.    I like finding new rural routes used mainly by the locals that start nowhere in particular and end the same way. Many in the area of that type are narrow paved and twisty, hilly and run through field and timber. Often along creeks or wetlands. Unfarmable areas of great natural beauty.    After years of this type of exploration they start to fit together. One ending a mile or so from another and you start threading together a new path from a unfamiliar place to a new adventure. Sometimes to a little town of under five hundred that used to be something before the Interstate or some railroad or US highway bled the life out of it that has a small dinner with the greatest slice of pie you've eaten since grandma made her last. A little village museum or library or even a town square park with grand old oak, walnut and Osage orange trees to sit under while you sip you gas station coffee and chat up some locals.    Often they are full of stories about the main streets more interesting buildings and the who's who of the area. Sometimes some hidden attraction or unseen history. Our area is full of old coal mines.     A younger self used to do this going cross country by motorcycle. Only a general area as a destination with no time to get there and no time to be back. Sitting at days end in a 10 unit off the main highway motel under a Sycamore tree yacking with the owner or his one semipermanent guest while I adjusted valves or the chain. Always a wave and a shout "Hey there stranger"!  It's how I came by my love of old Brit iron. There is no such things as a ten minute gas stop when your on a Enfield or a vintage Triumph. Same being true of old cars.    If you take the time to really look I've found everywhere is someplace interesting. Illinois or West Virginia. Different and yet the same.    People are in a more relaxed mood and will talk about anything and everything and if they like you there may be a cupp'a or a lemonade and a sandwich in it. 😉
