Ok Steve... Thanks. Thats a big help. I suspect that the connector(s) that I am looking for are actually the female connectors that run off the distribution male pins of circuit 30 (for optional equipment). It is located under the kick panel (drivers side next to foot parking brake pedal).
I suspect a break in the wire to the passenger door somewhere under the seat. I also suspect the female side of the red and white at the pump. Will check it out this evening.
