HOW TO: Making the low beams stay on with the high beams - '99-'02 GM trucks

[ScottyBoy]

This is how I connected mine, instead of a splice right behind each headlight. I made my splice beneath the underhood fuse panel for a much cleaner finished look. Here is where the yellow ground wires for the headlights meet up with the fuse/junction block.
Just cut it off from the junction block, solder on a piece of wire with a ring terminal and connect it to a ground bolt.

Now cover the solder joint with heat shrink tubing.

And just put a ring terminal on the end of the wire and you can connect it to this fender bolt directly beneath the fuse block.

Thanks AGAIN to Dan & Scotty Boy for the original write up and the fuse block tip.

I had tried this mod a while back and it didn't work because (as someone suggested) I must not have had the wire grounded good enough.

I am putting in new Anzo headlights ,new signals and new fog lights. Having them protected with Xpel and putting HIDs in down the road. So I figured I'd revisit it.

It didn't work at first. I re checked the ground and BAM. Good to go!

Soldered, heat shrunk and put it back together.

Glad my old posts are still helpful to someone.

And holy shit have my wiring skills improved over the last 3 years... I didn't realize how sloppily I did this, almost makes me want to go back and clean it up.

Almost.

It still works though.

We just thought you had finally gotten over the stroke.

question is there a with to keep the fogs on also?
Or should I say 6 high

You would just add the fog light 12v wire to the trigger wire.
I have a thread on here where I did this with just some diodes.

On the 02 models?

No mines a '04.

But you should be able a trigger wire as in the below pic.

I did the same as this but since I'm running wig wag I put a relay in so when the wig wag is on it goes back like factory. and it is see to turn on the fog lights and turn on the wig wag and the fog lights flash too.
