Tacoma wiring help!
Hello there!
I am helping my boyfriend with a motor swap: 3.4l 5vzfe motor into a 1st gen tacoma that had the 2.7l 3rz. Its almost perfect, runs pretty good, but we can't get the wipers to work properly. Probably because we're not great at wiring.
We think the issue is the wiper motor plug wires not matching up. The plug on the wiper motor is 5 pin, and the wiring harness we used (allegedly from a 2000 3.4l tacoma) is a 6 pin plug. They line up fine and fit together, but when you turn the key to the on position, the wipers turn on without you doing anything, and won't stop. If you try any controls it blows a fuse.
We have a gaggle of toyotas, and each plug and wire colours are different on all 5 of them.
My main question is, how the heck do we figure out which wires and pins on the harness are supposed to match up with which pins on the wiper motor?? I have a Multimeter but am not super savvy with it. I also dont have access to proper wiring diagrams, especially if the harness isnt actually from a 2001 (±1 year??)
ADDITIONALLY we could use a donor wiper motor and plug that match up perfectly, and can splice that plug into the wiring harness, but would still run into the issue of matchung up the proper wires...
Thank you if you read all that. I would appreciate any advice 🤟
