Hey guys, looking for help, couldn’t find any info on this particular topic.
I’ve got a 240sx s13 with automatic seat belts and I’ve sold them to a guy and part of the kit was the electronic module with its harness. I took it apart and it was mostly green and yellow wires going to the seatbelt motors on one side and the other side was going to the fuse box on the drivers side. Seeing as the harness was parallel to everything else in the body hotness except for the ground wire and a small red wire I figured it wasn’t a big deal if I just cut it and send it off the the guy who bought it. But now my car is completely dead and doesn’t respond to the battery at all, no relay clicks when I connect the terminals, nothing. Was running fine before. Battery and the main 75A fuse are fine. I think I might’ve cut the power wire going to the seat belt module and now there’s a broken circuit or something. There’s two main wires, white/blue and black/orange and I’ve looked in the FSM and white blue wire seems to be in a lot of places besides the seat belt module. What would I have to check with a multimeter and what can I connect the white/blue wire to to make the circuit complete again? Thanks for the help!

uhhhhhh, if it worked before, and you cut something, and it doesn't work afterwards . . . . one of the wires you cut was not something you should have cut.

start at the fuseboxes, make sure you have power to them, go from there and trace individual circuits. If you have the FSM, that's your best tool.

Power probe helps speed things up toohttps://www.jbtools.com/power-probe-pp3csblk-automotive-circuit-tester-diagnostic-power-probe-iii/?gclid=EAIaIQobChMI55WX1qik6AIVHB-tBh0HlQDQEAQYBSABEgK-1PD_BwE
