I've been looking for a 66 specific wiring diagram. I know that there are several diagrams out there that are billed as 66-67 diagrams but none seem to have the washer fluid button circuit on it. I have the button but the wires are just coiled up behind the dash. I know I could just hook it up to a power supply but I would like to know where it was hooked up originally. Also, I have three wires off the main harness behind the dash that are cut and I'm attempting to find out what they went to. The wires are Black/Green, Black/yellow, and Black/? ( cant tell because the previous owner got a little out of control when he painted the interior). Any source for that diagram?

didn't the '66 have a separate button for windshield washer? i've even heard of a foot pump near the dimmer.

Thats what I have. Maybe I'm blind but when I look at the diagrams on Fordfuelinjection and on N8's I don't see the button or the pump in the diagrams.

Looked at the old harness I pulled out of mine. I have a black/white stripe and red/black stripe? both seem to run to the plugs on firewall. One to each plug. If you can tell anything from that. Viperwolf should be able to help.

found the 66 diagram at sierrabronco. Looks like the power for the washer motor just goes to the spade connector on the fuse box. I also found that my cut wires Blk/Grn x 2 and Yel/Blk. The wiring diagram shows a "charge indicator light" Don't believe I have one and the original Alt is gone in favor of a 3G so I'm not gonna worry about it for now. The bad thing I found is that my washer pump is LOUD ! I can hear it clearly over the engine.
