Howdy all!
So in the attached picture, you will see the engine fuse box in my 1991 s13 hatch. The previous owner thought it would be an awesome idea to just cut off all the connectors that lead to the fuse box so now I am trying to figure out what they go to. The two thicker wires in the middle I confirmed are the starter wire and alternator wire. The 7 leftmost wires are the fuse box interface connections. However, what has me stumped is what are the three rightmost wires!? I emailed Wiring Specialties and even they didn't know what those wires went to. Any help would be greatly appreciated!

Thanks!

Hi...my guess is the positive wires on the white connector will be the main power supplies for the fusebox. That's why everything shut down when you disconnected it. Those wires will originate at the main fuse links inside the engine bay fusebox.
Maybe if you tell us what it is your trying to do we might be able to offer some advice?

You?re probably better off finding a harness from a car being parted...

Heres a little help:

Thick black with yellow to starter solenoid connector

Thick white to battery positive or alternator depending on which one it is

Yellow with white to oil pressure switch

Yellow with blue and yellow with black to speed sensor

White with red to alternator connector

Green with blue and green with white to reverse light switch

Not sure what the white with purple, the purple with blue, or that black with silver dot go to. Probably in the fsm. Probably have something to do with headlights. You could always split the fuse box apart and trace the wire
