I did that a while ago with my high and low beam HID's. Now that is bright, lol.

 

I want to do this to my 99, but can't see the pictures to know what wires to ground.

 

For a 99 like mine there are yellow wires in the plug to the low beam. You cut that yellow wire and ground it to the body. the side that goes to the headlight gets grounded. this worked for me.

i didn't do any of the other lights though just the lowbeams.

 

Just did the mod on my '00. Easiest mod I've done. I did it on the left headlight only and it worked, should I keep it as is or do it to the right?

 

ok so to make things clear....
if i want my fogs to come on during the daytime (brown line),
if i want my low beams to stay on when i use my high beams (blue line)
if i want my fogs to stay on when the low beams are on without having to use the button im assuming thats its still t4/b5 (brown line)

 

ok so now thats its dark out i have had the opportunity to see how the lights react when they go to automatic lowbeam.

i take it the fog lights are not supposed come on at night unless i push the button, of course now when i push the button the DRL comes on (which i love). until i click the high beams. then its just high/lows on. I just want to make sure i havent done anything wrong and this is how its supposed to work.

thanks in advance.

 

Can you do this mod with the late model trucks?

 

maybe i just missed it, but what gauge wire is everybody using to ground the yellow low beam wire on the 99-02? i have some extra 12 & 14 gauge at work, but i don't know if that'll be too much.

 

has anyone done this to the 08 + trucks yet?

 

I used a 14 gauge on mine, still beaming bright.
