First... if this is in the wrong spot I apologize and I searched all over the site for info on this and found nothing so I posted it.
So this is something that I have done to my GM trucks since basically all GM vehicles post 86-91 (depending on the vehicle) have alternating headlights. That is basically the low beam headlight turns off when the hi beams are activated. This just irritates me greatly and I always have to fix it.
Soo it took some studying since these cars are all wired HOT and the ground switches to turn things on and off. But I figured it out a couple weeks ago and have been testing, works great.
Now my low beams stay on, when I switch to HI. If you guys have all done this then I join the club, but if you guys need the info LMK I'll post a how to with pics I took last night.
