If you can find these Potter & Brumsfield VBA-1001 relays they are pretty nice for this application, they really reduce the number of connections, but they also use a special plug connector. The only source I found for these was TYCOs authorized distrubitor.


If you were wiring this relay in this is where the connections would go:
After disconnecting the two wire connector goint to the window motor...
A & F - connect to the switch side wires.
B & E - connect to the motor side wires.
C - connects to +12 volt 12 AWG yellow wire.
D - connects to ground.
my photo is not real clear, but 'D' is the upper connections and jumps over the connection that is 'C'.
