Foglights On With High Beams

In case anyone is interested. I was able to do this exact same mod on my 2017 Colorado. I followed the same process as @Spurshot to find the pins and what not. ANd then just used a diode, just like the one he used, to jump between the fogs relay and the high beam relay. The result is the same. Fogs on with High Beams!

 

The only difference being that the pin numbers on the brown connector in the Colorado are slightly different. Otherwise it's shot for shot.

Thanks for the inspiration @Spurshot

Is this the easiest way to have my fogs on when my highs are on in my 2015 Yukon?

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

Pretty easy, only took me about 5 minutes, once I had the diode and confirmed which pins I was connecting to. Now, my wife's CR-V and daughter's Cruze, they aren't going to be so easy.

On my 2015 Yukon, what do I need to do to have my fogs stay on with my highs? I clicked some links in this thread but they are dead.

 

All you will need is a 1N4004 diode ($0.98 @ Radio Shack, if there's one near you), needlenose pliers (maybe), and (I used) a small common jeweler's screwdriver. Also, you are going to need a diagram of your Yukon's BCM (not sure if Yukon is the same as Silverado/Sierra), so you know which pins to jumper.

Does this work the same as fog lights always on when low beams?

 

You can jumper that too with the same diode.

just curious... .has anyone bought fog light pigtails (5202 pigtails in my case with a 2014 Silverado) and tapped them into an hot fuse with ignition on to use the fog as DRL? then they would be on whenever the truck is on no matter hi or lo beam....

 

I am currently doing this to mine... i have the 5202 Opt7 LED bulbs in the fogs and will run the wiring this week.... (oh.. and I removed the spring in my headlight switch so i can run without my low beams as DRL, since I have HIDs installed)

Hopefully the direct power from ignition works to. I had success in my 14 with this mod but I've been jamming the little pin in and it's not working for me on the 17

I took one of my smaller phillips jewelers screwdrivers to make a path for the diodes, or even one of the small common-tip jewelers to help manipulate the diode's way into place.

My diode mods, from picture above. 1N4004 diode mods (strip toward second pin/wire):

GRY1 to GRY8 - Puddle lights on with all interior lights

BRN26 to PNK26 - Cargo lights on with Reverse (reverse the diode for R lights on with Cargo)

BRN18 to BRN22 - Fogs on with High Beams (Silverado's Lows stay on with Highs)

There are others for Park/Low on all the time, Fogs on with Lows, Fogs always on, etc. Believe the entire list is in "$50 and under modifications" thread, could also be in this thread somewhere.

I must not be doing something right..........can't seem to get the cargo lights on with the reverse lights.

I had the same problem. Yanked the diode, cooled off for a couple days, and tried again. Make sure that the stripe end is toward PNK26, and a good amount of lead is stuffed down in the hole. I used a fine tip jewelers screwdriver to help make room for the leads.

Nothing really to hold it in place on PNK26 since their is no wire in there. I'll have to try it again someday.

You may be looking at PNK27. All of the connectors on the BCM are numbered the same. PNK26 has a brown wire in it.

 

Black has 26.

Brown has 26.

Pink has 27. With #27 empty.

Grey has 26.

Ah, I'll have to check tonight. I didn't realize their was 27 in pink. Thanks! Silly me! :rollin:

      Cam chain tensioner question

      By B14Sierra · Posted

      So I'm in the middle of a DOD AFM delete on my 6.2 L86 Sierra. I had a pick holding the tensioner but after I got the Cam phaser gear off I was cleaning off all the rtv and apparently I didn't have the pick seated far enough in. I bumped it and the tensioner sprang forward.  I think everything is good but I want a second opinion. The top of the tensioner is just a looped piece of plastic that rides in that channel right? There is no spring or anything is there? I got the gear and chain back on and it seems tight and everything looks right. I'm hoping nothing fell out.

      No low range 4 x 4

      My 2015 1500 LTZ Silverado suddenly won't go into 4 x 4 low. It will go into 4 x 4 high.

      Transmission Woes :-(

      By asilverblazer · Posted

      Yep, just a quick reference point.    My main point being I’d do a thousand other things before I’d pay 10k for a transmission.    Speaking in ignorance cause I don’t look at these trucks, what is it worth? 20k?

      Intermittent no-code issues on 2022.5+ V8 trucks — what did the shop fail to capture?

      By asilverblazer · Posted

      I think users are going to want to pick their monitored parameters, which parameters they want to see first.    It should probably start with baseline at a minimum and adjust to learned, but be able to overlay baseline for comparison.   A simple severity level would be able to determine what type of alerting is appropriate or user selectable.    Why not use the OBD port though?   I think a phone connection would be a good idea, push notifications type deal.   Number 1 issue is having data is useless if you don’t know what the data should be under normal conditions.

      summer road trips in the 2026 2500HD

      By Chuck FB · Posted

      I thought I would use your thread and add to it as I just did my first longer drive with my truck in the last couple of days. I drove from the Grande Prairie area of Alberta down to Edmonton and most of where I drove in the city was the ring road so fairly free flowing but a bit of stop and go as well in the city. Stayed the night and returned home and not too many stops along the way each way but every restart and certainly every cold start sets it back for fuel mileage. Why I say that is I see some people will cherry pick a fuel mileage leg after the vehicle had been warmed up driveline wise before hand and its a forgiving ( easy rolling drive leg for example ) and call that their fuel mileage which can give a false perception of reality. I was not heavily loaded at all but never the less the flip bak cover, rubber bed mat, various tools etc and extra jerry cans of fuel all way up to a few hundred pounds of dead weight so its not an empty truck. The cold inflation tire pressures are set more near the freezing point so once they are warmed up driving I was showing 45 front and over 40 rear and realize high inflation pressures would help a little in fuel mileage but certainly not the ride on our crap sections of highway. The weather was good so was not raining as that can really drag mileage down, in fact I had a bit of a tail wind on average driving home. Most people on here would never have driven on that freeway to visualize it but its got a fair bit of rolling type of landscape with numerous river valleys. For the most part I had it on cruise set to 62 although kicking it off if I caught it in time before it started down shifting and self braking going down the grades. Most of the more substantial grades its shifting into 7th I believe as 8th just doesn't have it. Total distance round trip was 643 miles and my overall average and I did refuel three times in all, figured out to 17.65 miles per US gallon. My best fuel mileage section refuel within all of this figured out to 18.46 and these are all hand calculated figures. I find if anything that the trucks computer can be over optimistic, sometimes its pretty close but other times its stretching it. On paper persay in theory the truck would have just about made it on fumes for that whole drive without refueling once.    Which made me think of the topic thread of the wonder if these trucks could do 20 mpg and that is a good question, certainly would have to be on an easy going flat highway, no head wind, the right temperature, not packing around a bunch of dead weight and puttering along even slower than I was I would suspect and going steady and not stopping to smell the flowers or take a piss !. It probably is possible but not without effort to attain that with the wind resistance and weight of these trucks. Of course on my drive most people are passing me if they have the power as per loaded highway tractors, never mind a lot of speedy vehicles but the speed limit is 68 and most are at or well over that.
