I doubt this will work, but here goes:

Would someone with a FSM from an '89 TPI care please scan/type the pinouts for the connectors (2) that go to the windhield wiper motor/control unit?

I am swapping an '89 TPI/harness into my '87 Formula, and it turns out they changed the connectors at some point. I have the old connectors, so I just need to know which wire to splice to which.

Thanks guys!

 

Is it a pulse or non-pulse wiper motor?

 

Uh... good question. I thought for '87 they would be the same. I'll have to check on it.

Perhaps you are suggesting the difference is the '89 had a pulse motor, and the '87 does not???

 

Both years have pulse wipers, however I'm not sure about the location of the washer motor on the 87 models. On the 89 models the washer motor is located in the washer fluid reservoir. Also the wiring for the pulse and non-pulse wipers is slightly different regardless of the year.

 

OK, that makes sense. I wasn't so concerned (yet) about the washer motor as I am the wiper motor connections.

The motor is mounted in the same physical place on the '89 I took the harness from. Only real noticable difference is the shape of plug and the # of wires.

 

I can get you the diagrams, however I have a question for you. If the pins look the same but just have a different connector, why not just remove the pins and put them in the new connector and not mess up the wiring with splices.

 

That would be a great idea if the pins were the same (IIRC they were different too). Not saying it can't be done though, so I will try it out. I hate having to splice wires esp under the hood.

Thanks man!
