I have a '77 Ranchero that the wiper switch took a dump on. They are expensive if you can find one. I happen to have a switch from a '77 F-150 and I was wondering if anyone has a wiring diagram for this switch? And possibly the Ranchero switch. The Ranchero switch is a 2 speed pin type connector and the F-150 is an intermittent blade type switch. I plan to try and splice the switch into the Ranchero if I can figure out which wire goes where, on both of them. Any info would be appreciated.

 

You'll GET better info if you GIVE better info, like pics of each switch.

It's possible that the '77 is like this:
