My truck has two electric wiper motors, and each has it's own hot wire going to it's own switch, and then to each motor. I'm rewiring everything, and wanted to use just one hot wire and one switch to control both motors.
Will this work? I'm thinking because they don't automatically park, I'd never be able to get them to be parked at the same time, know what I mean? I guess that's the reason they each had their own switch to begin with. Or is there another reason?

Somewhere along the way someone put electric wiper motors up behind the header panel. Each motor has it's own hot wire feeding it and it's won switch, so they're independent of each other. It's just a basic on/off switch. There is only one speed (as far as I know), and they don't self park.

I bought a universal wiring harness and of course there is only one wiper circuit, but there are enough extra circuits that I won't be needing, like power windows, that I can use for the other wiper motor I guess.
