Windshield wiper motor connector

[Souleman]

Does anyone know where I can find an electrical connector for the windshield wiper motor? The kit did not come with one.

That's a good question, I have never seen one. I think your best bet might be to make your own from both sides. The kit as designed as you put individual connectors on the ends of the wires and plug them into the connector. That's what I did for 2 builds. You can kind of see it here. It has not been a problem

Check this connector. NOTE: READ THE WARNING IN THE DESCRIPTION. .010 can be easily removed/filed out.

In the past I've gotten them from the source that cannot be mentioned... But as already posted a connector really isn't mandatory. Crimp 1/4" spade connectors on the wires and plug them directly into the existing connector plug wires from the motor. Once the builds were done, I've never had the need to disconnect. So no big deal without a mating connector IMO.

I may have one I didn’t use. I recall finding one and ordered it. Ended up taking the wiper out and plugging the holes after inspection. I’ll check my electrical drawer. Yours if I find it.

Can we code name that place Voldemort?

Thank you for the connector links! I bought the one from British wiring which test fit well and looks like it will work.

Ok, so it's been a busy summer and the poor Cobra has once again been on the back burner. I finally got back after the windshield wiper wiring and ran into a small snag. Before I put all the connectors in it, I performed an ops check. Unfortunately, that did not go as planned. After blowing enough fuses to warrant buying stock in a fuse company, I finally narrowed it all down to what I believe is a parking wire issue.

The motor works as advertised in low and high, provided the parking wire is disconnected. This pretty much also tells me the wires are correctly routed. If I left it this way, I'd have to time it to get the wipers to park in the proper spot...no, it's not difficult and I don't plan to use the wipers, it's merely a Delaware requirement. However, I don't like it when things don't work like there supposed to...stupid OCD, so I'm trying to solve the parking function issue.

I checked continuity on the wiper switch and found the parking wire is hot when in the off position. I would assume this is the norm as when you turn off the wiper switch the park function would need power to put the wiper into the proper stow position. The continuity checks on the high and low positions with the park wire not receiving power. The switch appears to be in working order to the best of my knowledge.

With all wires connected and the motor in the correct parked position, the fuse only blows when the wiper switch is turn on (low or high). The fuse blows instantly, no movement at all.

With all wires connected and the motor is not in the park position, the fuse blows instantly upon turning the ignition key. It doesn't even try to park.

With only the park, power and ground wires connected, and the motor in park, it will not blow a fuse. Ran through all wiper switch positions with no issues, no movement obviously, but the fuse didn't blow at least.

With only the high speed wire disconnected and the motor in park, it successfully went to low and operated. The instant I turned the wiper switch off, the fuse blew.

Like I stated earlier, disconnect the park wire, and everything works like it's supposed to, except the park function.

My rudimentary trouble shooting seems to point to an issue with the parking circuit on the wiper motor.

I don't suppose anyone has any thoughts or insight to this?

I had a similar issue. I bought two different switches thinking the switch was bad. The switch was fine.

I went through a thorough troubleshooting and found that continuity at the motor connection to not match what it should’ve been. I ended up taking off the connector and parking switch at the motor. The switch blade and the contacts were not correct. A small bend in the contact blade and it worked!

The windshield wiper parking issue took me a little bit to work through, but it does work!

For me, it was simply that I read the connector and first tried it as I interpreted it, but then thinking about it, I decided to "mirror" the connections and it worked fine after that. The key troubleshooting step that caused me to dig deeper (and I think you discovered this, too) was that you should not get any current draw after the switch is in the Park position and the motor reaches that point.

I also got it to work with a rotary switch from Period Correct (it requires a separate relay) afterwards...

Good Luck!

Yeah, I've read that post so many times trying to wrap my head around exactly how the switch on the motor works. I totally believe I have an issue with the parking switch on the motor. My initial thought is the parking terminal is grounding out when engaged (off "bridge"), hence the blown fuse. The next move will be to take the switch off the motor and take it apart. I imagine the parking switch is designed to shuttle power to the low speed circuit which gets interrupted by the "bridge". I only see three terminals off the back side of the switch going to the motor...which I assume to be negative, high and low speed power. After reading the posts and studying the pics, I just haven't figured out how the motor switch is transferring power and why it seems to have an unnecessary terminal. Guess I'll figure it out once it's all apart.

Josh,

Here’s what I found on the FFR site.

https://www.factoryfive.com/wp-content/uploads/2021/03/WIPERS-Roadster-rev-P.pdf

(See page 12)
According to their diagram, you should have four terminals to the motor from the switch, not three.

Yellow=Park
Green=Low Speed
Brown=High Speed
White=12V Power.

Then, from the motor, you should also have a ground (of course) and a wire from the same terminal as the power lead to your fuse panel.

I bought this one and sure enough I had the exact issue mentioned in the warning (at the time I bought it, it didn't have the warning). It looked like a lot more than a .010" interference...I tried filing the connector opening a but but could never get a single spade to install into the plug, let along all of them. So I abandoned the plug and just plugged the spades in. Works fine.
