Ok, first of all I would like to thank Jetsetmantony for the info on the Heater Switch. Now I will try to explain my next problem. Ok I am trying to find out where certain rear terminals go to a single speed with washer wiper switch. I believe my old harness was connected to a single speed switch only because I only have 4 wires a blue, orange/black a black, and a white. On my diagram it shows a orange / white wire from the ignition switch accessories I cannot find it on the old harness anywhere it may have been cut off . Okay, my new harness is a Ron Frances and my question is I only have one wire a purple one that says wiper and it comes out of the fuse box not the ignition switch. The wiper switch I have has 7 terminals on the rear . The very top one is where the orange/ white wire should go if I had it and below that is where the blue goes, and down from it orange/black and down black and down white. Okay since I do not have the top orange/white wire does the purple wiper wire connect here top instead? and now I have two terminals left I assume they will connect to the wiper washer pump the one I have has two wires on it? Maybe a hot and the other a ground to the pump? I am sorry I probably got everyone very confused. To break it down I am wondering where the new purple wiper wire from the fuse box connects and what connects to the last two terminals . Thanks Very Much Everyone!!!!!!!!
