Conversion to 3 speed wipers

[2cudas2go]

Hi, I would like to know what else would be required to do the conversion. I already have the wiper motor and the arms that go behind the firewall. This is on a 71 Challenger Coupe

Thanks,

I'm in the middle of the same conversion on my '70, and unclear of any differences.   The motor/arms you have.... what about the switch?   For a '70, it is my understanding that the wiring behind the switch is ok... no changes needed - but I'm not sure about a '71.    Remember that the switch must be properly grounded for the wiper to park.

Do you have the correct crank arm from the motor to the linkage?

This is what I have plus the 3 speed motor of course.

Thanks for your help.

You just need a switch.
