okay. i got it figured out. I just needed to step away and come back to it. when switching out the seat sliders 2 of the motors come off with the wj seat slider/frame, but the backrest motor is retained. it is bolted t the seat itself not the slider frame. I've now got both passenger and driver side seats in with the xj manual slider for front to back adjustment.
one more question though. now i need power so the backrest can be adjusted. for the wiring i found (from the FAQ sticky) this thread on NAXJA http://www.naxja.org/forum/showthread.php?t=1042180
but i can't tell which which part of the wiring harness is being used or how to wire the driver side and passenger side together? has anyone found a thread that would help someone with no electrical experience accomplish this? thread with pics would be awesome.
