My car's not on the road, but I recently installed electric driver's side front and rear quarter windows in my '68 Camaro. Because I was also installing the glass, I had to rig up a little wiring harness to power the motors while adjusting the glass. My temporary harness was about 5' of 12 gauge wire from the window switch to the motor wiring, and another 5' of 12 gauge wire from the window switch to the battery jumper cables that were hooked up to a 12v car battery. While I'd heard about the "wimpy" performance of the Electric Life electric windows, I was very impressed - again only during the glass install and adjustment process - with how quickly and powerfully the electric motors powered the windows up and tight against the weather stripping, even with the door closed.

However, and it's a big however, I was much less impressed with the wiring harness - which (IIRC) routes the power for the front window through the rear window switch in what looks like 16 gauge wiring. The harness is fused for 25 amps, and if the window motors are drawing 20 amps, the wiring should - given the length of the wiring runs - be sized at more like 12 gauge. I suspect that if the windows are "wimpy" it's because they're not getting enough juice. I'm still trying to decide whether to use the Electric Life harness, or to wire the windows more robustly from the start.
