Power Window Relays
Ok, I was trying to figure out the wiring for the relays for the faster power windows mod.. I can't figure out the relays in this diagram:
I can't figure out which wire goes to which part of the relay because the relay in the picture is not numbered. Has anyone done this mod? Where does the hot wire go, ground wire, switch, etc? 30, 85, 86, 87, 87a?

well if you will look at the picture you will see that there are three prongs on one side and two prongs on the other side of each relay. The purple and green wires go to the two prongs on the one side of their respective relay. Across from them will be the ground wires and the odd man out will be the last prong that has nothing opposite it. That will be the hot wire.
