I'm trying to figure out how to hook up a set of 06 XSP power seats that I bought on eBay to an 03 SR5. Sounds like it can be done, using the existing 03 SR5 harnesses, but I desperately need help with the wiring. Thanks!
There are wiring diagrams on here. I did not document when I did it, but found the diagrams for the seats and spliced accordingly. My wiring is all taped up/enclosed and zip tied or I would take a picture. i did not buy 06 connectors but used standard female crimp connectors. I then taped up the connectors. I had to wire the heated seats to the fuse box and add a relay. good luck.
