How do I do the 4 high mod? Is it the same thing that I have done on my 2000 yukon?

There is a plate you put in the fuse box ... not sure they make it anymore...I forget the name. @05Single may know or @Rocket Man

I just grounded the yellow wire on the low beam but that’s only for 00-02 afaik.

I just installed it recently. Used the fleece performance plate: https://www.amazon.com/gp/aw/d/B019JDFGEI?psc=1&ref=ppx_pop_mob_b_pd_title

You can also use diodes to do it, but this is the quick, no brainer method.

ETA: Not a great picture, but this is 6-high, with the fogs:

Tapa.. tap.. tap dat.

Not on your 2003. 99-02 is ground the wire. 2003-2006 takes a bit more.

Diodes get you the 6 high and I like the fogs being on when I turn on the lights (or when Mr. computer turns them on). Wish fleece would make it 6 high then I would buy it.

I’m confused. The fleece chip gives 6 high. (High/low/fogs) fogs still work independently. Lows still work as normal, but high switch (forward, or back) gives “all on”=lows/highs/fogs. Sounds like that’s what you’re after?

Maybe I misremembered when I looked at them last except that when low beams are on fogs are not unless you turn them on. I like them to be on automatically with the low beams. I suppose if I got the fleece I would only need one resistor jumper.

Fleece is the 6hi . Only thing you can do differently with diodes is make an 8hi and have the drl’s turn on at the same time.

Also on the 00-02 we can do the full time fogs and full time drl. Mine works like this: drl’s are always on. Turn on headlights (low) or park lights and fogs come on also. Hit brights and all the aforementioned lights stay on so now I have 8 lights on. All are LED and color matched except the low beams are HID in Denali projectors. I’m sure people wonder wtf is behind them even with just the low beams, drl’s and fogs on. It looks a bit intimidating lol. The only thing with the Fleece I don’t like is it only activates the fogs when high beams are on unless you manually turn them on.
