Hi,

How to hookup the power window? (my car doesn't have them originally)

I have had to replace the passenger side window on the front of my 240 DL volvo 1986. Instead of going to the trouble of replacing the glass, I just went and bought a whole door from the junkyard. The new (to me) door has a power window, I have already installed the door and there is an extra plug on it that has three pins, this I assume is for the power window, (since the other two plugs both matched from the original manual window door hookups). In the fuse box area on the drivers side there is a slot with a fuse labeled "power windows". Also there is a TWO pin socket on the metal box thinggy on the passenger side that seems to feed all the engine stuff through a hole in the firewall, anyhow that two pin socked is capped with another socket that just loops back into itself. Is that maybe the power for the power window? Anyway, since I only have one power window, can I just run power to one of the pins on the three pin connector on the door? It looks like two of the three pins have the same color coding for the insulator of the wire. I guess I don't really understand why there would be three pins for the power windows either. Wouldn't there be just one for the power, and another for the optional control from the drivers side?

Thanks in advance!
