Wiper Wiring
I have a 72 project. It has a wiring harness from American Autowire which provides one grey wire as "wiper feed" This car came with a modification that eliminates the wiper door, and I think the limit switch. From my inexperienced eye, think I need to run the grey wire to the yellow side of the switch? Then from there install a relay, then to the motor? Theb blue and green seem to be high and low speeds? Then how to switch washer?
Bottom line is I am hoping there is someone knowlegable about general wiper wiring and not specifically C3. Thanks!

Let me try this again. In the Wilcox schematicthere are 3 wires on the switch. I believe the yellow is the hot to both the motor and pump? The blue and green are both labeled common? Knowing that much would be a starting point. Thanks
And Allan, that looks like one pretty car. Nice work
