    I finally did the power window wiring set up with 4 relays. Before I needed to race the engine to just watch the windows just creep up and down. Now, with even the engine off, the windows go up and down about as fast as a modern car. I was impresssed at the huge difference. If you havent done it yet, I highly recommend.. you dont know what you're missing.

    And here's how it looks in a second gen:

    I think I have to give it a try.

    Thanks for the info. :bowtie:
    I was looking for a way to nix the old relay but it makes sense to use it as a 12V+ trigger.

    I suggest you PM BonzoHansen and have him add this to the Electrical Stickies.
    This is most definitely a keeper that EVERYONE can benefit from.

    Great timing! I am preparing to wire up the windows next week (hopefully) and will definitely add this idea to my car.

    I wired mine according to the schematic posted by zekefreak and I know now it works and works great with the 4 relays. I didnt use the old factory relay (it was long gone) and I wired the main power wire to the horn relay on the firewall with a 30amp breaker so it gets power right from the battery.

    Holy crap.... that video shows the window going down really fast. Is it just me, or does it look like the motor is hesitating briefly as it lowers?
