Currently have 2 spd. wiper motor in my 71 Chall.
Am looking to install 3 spd. motor. I have the 3 spd. motor / switch/ linkage .
I'm looking for the wire harness to the switch. Any help/ leads appreciated.
Does anyone make these New?
Thanks in Advance

Your existing harness will work just fine. I didn't need to change mine when going from 2 speed. This applies if you have the correct 1971 switch 2770380

Thank you for the pics. As you probably know the more you get into this the more you learn .I have 2 sets of wiper links. Both are supposed to be 3 spd. Any light you could shine is appreciated
2822 292 58622
3431 514 58622

I layed 1 set over the other and they are the same?
Any thoughts?

2822 292 is a 2 speed link, not to be used with a variable speed/3 speed set up. 1970/71 used a 2822 293, rare and hard to find.

3431 514 is a 3 speed link for 1972 to 74 3 speed setups. It would work with the correct 72-74 crank.

In 70 & 71 the 3431077 wiper motor used a 2822289 crank.

Thank you again.
The crank on my wiper motor (3431665) has part # 3431518 on the crank.
Thank you again.

Both those are 1972+ parts. Seems like everything you have is 1972. If your switch is also a 72 and up 3 speed one then you’re right about your first post. You’ll need a different plug for the switch.

Sorry, I thought we were working with ‘70 - ‘71 stuff, your nickname led me down that path. I saw your other thread too, that’s also a 72+ rallye cluster.

If you have switch #4 you'll need a new connector. If you have switch #2 (2770380) your existing harness is fine. Variable switch 2770378 will also work, it looks identical to #2.

Thank you for all the helpful info. Any chance you have a 2770380 switch you would sell.
The 2 switches i have are 3 spd. 3488764 and 3438764.
Thanks again

Yup, those are 1972 switches (typo on the second number). Sorry, no I don't. Those would be pricey too, of course, depending on the condition. You might have better luck with a 2770378. Maybe someone has a 72+ donor harness and are willing to part with the plug. Then you can re-pin it according to the schematic in Post#7. Here's what I believe to be a picture of it. Your very welcome too, glad I could be of some help.

would that work with my motor # 3431665
Thanks

I'm guessing it would. Things I've read in the past said that a 378 is a suitable replacement for a 380 but they were all talking about the 3431077 wiper motor.
The other thing I came to believe was that that big plastic cover on the 3431665 motors merely houses a set of more robust contacts that replaced the flimsy ones under the 3431077 motor's top plate. Sorry, but I'm mostly just familiar with '70/'71 stuff.

Can anyone else please verify that the 3431665 motor is basically the same as the 3431077 one.

When I did my 2 speed to variable/3spd swap I went the extra mile replacing the washer foot pump with the electric pump. That feature was built into the switch. All it entailed was a new reservoir, washer motor/pump (wiring was already there) and a new firewall grommet. Something to think about.

It was the final step that went with the standard to rallye dash conversion.
