I've got power windows and power door locks and highly reccomend them both. I got both kits and the switches from A-1 Electric - http://a1electric.com/classics.htm - and was very pleased.
The power window kit installation is very straight forward. The hardest (most time consuming) part was running all of the electric wire.
Out with the old window regulator, in with the new. The new electric regulator just bolted right in. The install was very easy and the windows work great.
The hardest part was the wiring. Also, now that I don't need a window crank, I'm mounting a tweeter, for my component speakers, in the hole in my door panel.
I bought mine from Electric life as well. I also put the GM style rocker switch on the center console for a cleaner install. I also used a quick disconnect at the door jams to make future door removal less painfull.
Has anyone tried these universal power window kits? I live very far from the states and shipping on the power regulators would be more than the regulators themselves. Tell me what you know about the universal power window kits they sell on ebay? I was considering the autoloc version, but have included 2 other types also below. Autoloc was great for my import racer but want to hear some stories before I decide on which one to do.
Haven't tried them in my Mustang but my son had one of them in his MR2. I don't think they would work in a Mustang because the regulator doesn't have anything on it to be driven, other than the crank, and its gear is totally shrouded. The kits specifically for Mustang have the motor right on the regulator teeth.
