New Wiper Motor

[PenGun]

I have a new Motorcraft Wiper Motor for my 93 Mark VIII. Everything is fine but the wiring does not match up. On my car there is a 4 pin main connector and a 3 pin one that goes in the side of the motor. The new part has one 7 pin connector and when I look at the ones on line I see there is a wiring kit included with many of the rebuilt ones.

I am having trouble finding stand alone wiring kit and I wonder if anyone has a schematic detailing the pins and their connections. I could just solder pin connectors to the wires then. My scanned manual is useless for this.

A word to the wise and a reference for the pitiful search engine here and also for Google.

The 93 and possibly all Gen 1 Mark VIII come with a wiper motor that has one 4 pin connector and one 3 pin connector. The replacement Motorcraft wiper motor has a 7 pin connector.

Make sure you get the wiring kit with any motor you might buy. Only the new Motorcraft motor does not come with the kit. All the rebuilt ones appear to have the kit. I opted for a new piece and now I have dropped another $80 for an adapter from Ford parts. They have an obsolete dealer they use. It would almost have been worth getting a whole rebuilt motor as well just for the kit. Almost, but with shipping not quite worth it.

Sounds like that should have been a junk yard find (wire harness) then you cut and splice.

We have had 2 Mark VIIIs in the local yard in it's entire existence. They are very rare up here. Long gone.

As well you will only find the wiring kit on cars which have had the motors replaced. The original factory wiring is the 4 and 3 pin setup. The replacement motors are all 7 pin or so my Ford parts guy believes.

I'm not sure what the other year Mark VIIIs have for wiring but the 93, and I suspect the rest of Gen 1, is like that.

Anyone?

Gen 2 is 7 pin

Yep, when I replaced mine in the '93, it had the pigtail and instructions.

Word I heard is the early years were not getting enough cores for the remanufacturers.

The 94 is even different from a 93, I found out ...

OK. The 3 and 4 wire connectors are combined into the 7 wire connector thusly:

Looking at the 7 pin connector from the back with the catch on the top we number from right to left (not left to right) 1 - 7.

The 3 wire connector (these are the car connections before the pigtail bit):

7 is White
6 is DB/O
5 is Y/R

The 4 wire connector:

1 is G
2 is BK/P
3 is R
4 is BK

May this be useful, oh ghods of the search.
