The Stovebolt Site Forums The Shop Area The Electrical Bay wiper motor conversion

Thinking of trying to adapt a 1993 Jeep electric rear wiper motor to convert & eliminate the excisting vacuum wiper motor. Wires in the harness are as follows.
BLK/Wht
BRWN/GRN
BLK/PNK
BLK
BLK/ORGN
Wondering if anyone knows the job of each color? Or perhaps someone has a wiring diagram?
Appreciate any help anyone has to offer.

Don't know if that motor will work but a Jeep dealer should be able to tell you what those colors correspond to.

Hook it up to a wiper switch and check each function. One is power, one is ground and most likely two go to the control switch. Get the correct switch and it will tell you a lot. I'm not an auto electric guy but this is fairly simple in my thinking.

Thanks Wally/Montana. The jeep dealer here told me they only keep 10 yrs of technical stuff in their system and couldn't help out with a diagram for my 1993 donor wiper motor. And as 53Moneypit sugested, using a wiper switch would be fairly easy to do trial an error, problem is I have not been able to find the right switch.
Plan "B" I have figured out how to make it work with a simple toggle switch. Just like the original vacuum motor It will have 1 speed. If I get lucky enough and locate the proper switch I could always hook it up and have delay and 1 extra speed added.
In the meantime I have been working on mounting the donor wiper motor and it looks like it will be in place today. I will be adding pics and explanation sometime in the next few days.

What model Jeep?

I would like to share my solution for a vacuum to electric wiper motor conversion. I was not able to find the popular rear donor motor from a 90's Blazer or Jimmy. I brought home 2 rear glass hatch door donor motors to experiment. So I horse traded a salvaged heater core I had in my garage and we made an even trade for the 2 junk motors.1 Jeep Wrangler and 1 1993 Suburban. First thing I noticed, was how much longer than the Blazer the shafts were on both. I thought why not mount it in the same spot as the original!

I chose the Jeep motor. Starting with flat steel, 1"wide x 1/8". Drilled a hole on center to except th end of the motor shaft & a welded 5/8" lock collar. Reference the original vacuum motor and found that it had a 5" distance on center between the 2 mounting bolts. Drilled out the swivel plate the same as original distance.

New bracket to secure Jeep Motor

1" pipe x 2" long cut in two.(trim to fit later for clearance)
Cut 2 pcs of 1" wide x 1/8 flat steel to approx 3" lenght each
slot pipe halves to accept the flat steel, weld.
Weld ears on pipe halves to bolt and squeeze clamp to motor shaft. Dry fit,cut & trim for clearance. This method allows for fine tuning and clearance. Works well and will give fellow stovebolters a chance to use other donor motors not previously mentioned. This I think is a very cheap and dependable solution for anybody that would like to attempt this fun project.

I just finished a conversion using this boat wiper motor:

Works great. Has 2 speeds and parks itself. Adjustable sweep of 80, 100, 110, and 120 degrees. Followed this guy's writeup for the Blazer motor conversion. I could not find the Blazer unit and another poster suggested the marine unit.

Hugh 55trk I was wondering what this motor is worth. Sounds like a very good solution as well.

The marine motor from ebay was $60 plus $10 for shipping, $70 total. Still less than half of some of the conversion motors. You do have to do a little work to transfer the arm from the vacuum motor to the new electric one. See write up for info.

Not stealing the thread,but wanted to throw my 2 cents in.
I'd been wanting the Newport Eng. conversion since I got my '54 because I've been told how good their products are,so I finally bit the bullet and bought one directly from them. I didn't have time or energy to fabricate a set up,though I do have a couple of universal wiper motors from a motor home on the shelf.
It was relatively easy to install and works great. I learned the easy way to reach the mounting screw on the passenger side of the motor was to remove the cowl vent-then I could lay on the hood and reach right in there to tighten it. This might be a "54-E.'55 GMC only" issue.
Merry Christmas,everyone!
