    4-hi headlight mod.

    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.

    Got Light?

    For the record . . . .

    AMY has all four lights come on at once.

    But the toggle is between high-beam and fog.

    If the high beams are on, the low beams are also on. Perhaps someone can confirm if that is always the case with mini-quad cars (Grand Prix and Cutlass Supreme coupes).

    Cool beans. I'll write this up tonight when I get home from work.

    This mod should work on virtually all W-body GM quad light cars that are negative switched.

    Glad I can help out.

    This mod for me would be useless there is ALWAYS someone else on the road, and with the Intrigue to use all 4 lights just pull back on the stick and hold it in place. This will last all of 15.1 seconds until you see another car approaching in the oncomming lane.

    i already stated how to do this several times.... it is easiest on non-DRL cars, and involves splicing two of the wires for the headlight dinner switch together.
