71 Duster 3 Speed Wiper Wiring

[KS Hcode]

I searched and could not find what I was looking for. I am completely rewiring this car as it was a drag car shell and had nothing. I am using a 3 speed wiper motor to help with clearance for my 6 pack set up.

Can I get some help with wiring this switch up? My diagram only shows 2 speed switch. The wires coming from the motor are in tact. The switch I have has the letters clearly marked. The under dash harness I bought also only had the 2 speed plugs.

Any help would be much appreciated. And I know I should buy a service manual….

You've got a 72+ 3 speed switch, and your '71 would have used a 2 piece connector and used a variable speed switch (same motor though). You'll need to source a variable speed switch and re-orientate your dash harness plug(s) to fit the footprint of the variable speed switch. The same plug(s) in 1971 were used for 2 speed and 3 speed applications. Manipulate them and they will fit together on both switches.

Or.......Source a 1972+ dash harness and disconnect the wiper wires from the plastic connector and use the plastic connector with your 1971 wires. Good luck.
