Hooking relays to Electric Life Power Window Kits - 69 Firebird

[ModernMuseum]

I have a set of crappy Electric Life window units in my 69 Firebird all around. I know the Nu Relic units are a lot better from what I've read. My windows don't roll up very well and drop crazy fast when rolling down.

However, a more economical fix might be to hook the switches to relays to get more power to the window motors. Has anyone done this? Is it worth it?

Anyone have a diagram of how to do this?

Where are you getting the power feed? I find that you get better performance if you run the feed with a heavy gauge wire directly to the battery to minimize the voltage drop. It also helps a little if the car is running.

Not sure; I'll have to check. Are you running Electric Life window kits?

Looking at the Nu Relic kits, the harnesses / switches don't look any beefier than the ones I have. I am thinking I can get buy with upgrading the motor/gear units and keeping my existing wiring harnesses/switches.

The wiring is inadequate in both kits imho. I use NuRelics and run power to the battery with a large gauge wire.

To verify wiring simply put a voltmeter on one of the motors and measure the voltage. In theory it should be close to the battery voltage.
