240sx 1989 motor wiring help

[Dwolfe]

Hey guys fairly new to the 240sx seen and i recently picked up a 1989 w40sx hatch, with the stock ka in it . Older guy owned it and was gunna yank the shell off and use the frame, but decided not too. He cut the chasis harness right were it enters the fender. So should i try to solder the harness back together? Or scrap it trying to save as much money as possible. If i have to solder it? Anybody have a good diagram? Of the wires? Also were are all the grounds on the harness? Thanks guys

Ouch, that sucks man. If it were me, I would find a complete harness. With all the swaps and even going from SOHC to DOHC, there should be some available for you to snag pretty cheap. If you want to try and solder it all together, I would find a FSM with all the complete electronics layouts.
