Nice write up! All I need now is to know how to wire it up and I'll be doing this to my 4 door!

So I received my Integra wiper motor from Rockauto today, p/n WPM5423 ordered for a 1999 Acura Integra. You can see that it's a little different compared to the one Spriso posted above. The gear cover is plastic and there's external wire junctions on the cover, whereas Spriso's has a metal cover and no external wire junctions. Also, the wire colors are different.

I suspect the differences are aftermarket (Rockauto made in China) vs. OE, and this may be a Honda version because I found a Del Sol wiper motor schematic online (sorry no link, I just wrote it down), and the wire colors and pinouts agree with this motor. Here's how the connector is wired for this motor:

Image

By inspecting Spriso's photos and comparing, you can see that the wire mapping goes like this:

Viewing into the mating end of the male motor connector, and using the following pin numbering convention,
1 2 3
4 5
the pin assignments would be:

Pin, Function, Integra, Del Sol, 510:
1, HI, Blue/Yellow, Yellow, Blue/White (LW)
2, LO, Blue, Green, Blue (L)
3, GND, Blk, Blk, Blk (B)
4, PWR, Green/Blk, Red, Blue/Red (LR)
5, PARK, Blue/White, White, Blue/Yellow (LY)

Now for the unexpected surprise: The 510 wiper motor mounting plate bolts right up, no clearancing required! You can see in the second pic that it is close to interfering in a couple of spots, but it clears!

Here I've attached the 510 arm, and temp installed it on the car:

Now I just need to obtain a factory 510 motor male connector (my donor motor's connector is sadly perished), and wire it up. With the requisite serviceable donor 510 wiper motor parts, this is a true bolt on upgrade. A minor miracle, actually...

Vintageconnections.com has your connector shell and pins. Great find. Thank you.

Equipped with the proper connector bits (thanks Michael!) I cut off the modern connector from the new motor and crimped/soldered the spade contacts to the wires and then inserted the contacts into the 510-style shell.

Here's pic of the connector plugged in to the wiper connector on my '72 harness where you can see the wire colors on both sides, and a wider shot showing the wire table I made for reference:

Since this is for my '72 project car which has yet to be fully wired, I tested it on my other running/driving '72 and it worked flawlessly! I had both LO and HI speeds and the PARK function worked perfectly. Stoked! I added a strain relief to the pigtail to protect the soldered wire terminals on the gear cover from getting yanked or flexed to the point where the wires might break off. Here's the final installation on my car:

Big thanks to Spriso for laying the groundwork and sharing his research on this most excellent wiper motor conversion!

Yes thank you both! I ordered a used motor off Ebay primarily to have the metal zinc-coated cover to have it match the original as well as possible. A new one was NLA according to my parts guy at Honda plus would have cost a bunch more. Will clean it up before winter and install using Tedman's wiring directions.
Carpe Diem!

I finally got my wiring corrected on this upgrade. I can't upload the wiring diagram so if anyone wants what worked for me with the acura wiper motor and my stock '71 510 connector, send me your email and I'll send you the diagram.

Please use the email below.

Excellent information everyone who contributed! I need to do this.

Lots of parts on ebay right now, including new for less than $50.

Thanks.
