I have a '70 Dart and am converting from the 2-speed windshield wiper set-up to a 3-speed wiper set-up.

I have a 3-speed motor coming any day now from Jules, and I have a 3-speed dash switch as well.

From the prongs on the switch to the linkage that attaches to the motor what do I need to change, or do differently than the 2-speed to make it work like factory?

Thanks for any help!

Better look at the FSM and the wiring harness - I believe the harness may be different all the way back to the switch. The wiring from the firewall to the wiper may be on the wiper motor harness, but the part back to the switch may be different...

I would assume the switch harness has to be different. I know the 3-speed motors have a harness that plug into the bulkhead at the firewall, but I believe they may have another portion of harness that snaps into the motor's plug facilitating their contact into the bulkhead and then those wires route around the engine bay somehow.

Thanks for your response!
