3 speed wiper wiring

[Crider]

I'm in the process of putting my dash back together and I'm converting to 3 sped wipers. I've read that I need to add a wire to the switch, but where does the other end of the wire go?

Your wire harness should have the additional wire already there but you will need the 3 speed switch.
Read through this thread, it may help

Ok. I have the correct switch. Just wasn't sure because the switch has one more spot for a wire than I have wires. Guess I should have also added this is for a 69

Also see here, more to it than just the motor and switch, you need to change the crank arm.

If you put "3 speed wiper conversion" in the forum search field, there is a ton of good info on this swap

Thanks Bill. Looks like that 7th terminal isn’t used. I already have the 3 speed cranks arm. So it looks like I should be good to go

The 3-speed switch uses the same multi-wire connector as the 2-speed plus one added single wire connector which is usually taped up on the harness. And yes, there will be one unused terminal on the switch.
