I know the GM900 GMC Sierra fog light upgrade subject has been brought up before, I have read them.

The problem I have is, where are the wires under the truck to plug them in? I have installed the OEM fog lights and installed the new headlight switch with the fog light button. I have also ordered the two harness pig tails part #15789984, I can't find where to plug them in. Does anyone have the instruction sheet from GM for the upgrade that shows where they are hiding? :(

 

Thanks

The trucks aren't pre-wired.

 

did you buy the whole retrofit kit pn 19170447 with the wiring harness? it sounds like you just bought two lamps and the switch, in which case you will need to get the wiring harness.

You are right that is what I did. I attached a diagram that I have. It shows the pig tails as #8. That is what I ordered part #15789984 and looking where to plug them into, is there more? Is there another harness that I need and if so do you know the part number?

 

Thanks

I don't know the p/n. I bought the 19170447 which came with it. I will look this weekend (pouring rain) for a part number on the wiring harness, but I suspect you are best going to a dealer and having them look it up, as I don't recall any tags on the wiring harness.

The kit comes with a special harness that goes from the wire at #8 to the fuse block under the hood. The dealer should be able to locate the harness on the parts fische. Or maybe they can get a list of what parts are in the 19170447 kit.

      The engine was done as part of the 6.2 recall?   You'd have to see if your VIN also has the 6.2 engine special coverage on it.  Coverage number is N252494003.  If you have this, your engine is covered under this and NOT the GM replacement part engine warranty which is 3yr/100k from the date of install.  The 3yr/100k mi warranty is in effect for non warranty purchases.     This is not any different if it was replaced under warranty without a recall or special coverage.  So if you had a 5.3 and it popped at 3 years in at 50,000mi during the 5yr/60k powertrain, the replacement engine would not get the 3yr/100k, and instead gets the remainder of the 5yr/60k as coverage.     So N252494003 gives 10 years or 150,000mi of coverage, which ever comes first, starting at the vehicle in service date.  So if your in service date is 01/01/2022, N252494003 gives you special coverage of the engine until 01/01/2032 or 150,000mi, whichever comes first.  So if your start date was 01/01/2022, you'd have left 5 years and 4 months (lets round to august 1st), or 62,000mi left of coverage.   So you need to know your in service date to know how much coverage is left.

      Injector update

      By CamGTP · Posted

      Okiee dokie there bud, way to take things to the extreme.   I guess you missed the whole point and take things way to serious. I installed different EV6 style injectors that just so happen to be larger in my car running the same LQ4 engine and with a better spray pattern than the stock style injectors and I noticed no difference in the idle quality. Kinda was my round about way of saying that even if you put the same size but better style injectors in your truck, you will likely see the same thing.    I'm sure you're great to have conversations with in person if that's how you act through a keyboard. One little things sets you off and now I guess my dick is all up in your face.

      I can't believe that could possibly be the case. It should be 36mo/100k miles from installation. Then again, it also seems like since a dealership installed it, it'd all be in the system and you wouldn't need to worry about registering, either. Shows you what I know. 😄 Hope this one outlives the warranty!

      I haven't seen inventory recovery from COVID.    In the few random times I 'build my own' truck or SUV, no one has the exact one I want.   GM has been working to lower incentives too for a long time.    A $500 incentive isn't getting me off the couch to go truck shopping.
