Electrical Help/Questions!!!!!

I tried the mymopar site, that's where I got some of the schematic prints, PLUS the shop manual for the car. NONE, mention a yellow wire. I had an idea, I checked through all my pics and found ONE, of the starter relay with a very dirty yellow wire attatched to the back side of the relay. Now I just have to find the connection for the washer pump.

I wish this was done now!!!
