Variable wiring
« on: June 27, 2008 - 02:52:41 pm »
I had bought a beautiful chrome wiper motor from Jules and had to find a variable switch to run it. I found one but the wiring for my car is for a two speed. How do I wire the extra prong in the back of the switch to make this run right?

No amount of cleaning work I did could get my firewall contacts clean so I just wired mine up directly.  If you have a wiring diagram it shouldn't be much of a problem to get it all straightened out.

On the variable switch, there will be one prong left empty (pretty sure it's the B/U prong on the edge that is a ground), but some wiring has to be changed at the switch. There are little letters molded into the back of the switches.  You might need a magnifying glass to see them. If you refer to the wiring diagram, you'll see that...
the red wire that went to "A" on the 2-speed goes to F-1 on the variable switch. 
the brown* (w/ stripe) wire that went to F-1 on the 2-speed goes to "A" on the variable switch.

There is NO difference in the wiring at the switch.
