Give you a basic run down. Car is a 93 with power everything and a blacktop sr20 swap.

After a few months of owning the car random electrical issues started appearing. First it was the fuel pump not working, I ended up just hardwiring it with a relay off the ignition and it has been like that ever since.


Then a bunch of electrical issues appeared at once:

Rear turn signals don't work and the bulb on the cluster doesn't work, but the fronts do work. Hazards do work and the bulbs on the cluster do light up when the hazards are on.

Speedo stopped working.

Reverse lights stopped working.

Headlight motors don't work.

Intermittent wipers, the wipers work but the intermittent does not, just on or off.

Power windows stopped working but I think its just the window amplifier in the drivers side because the passenger side does work.

E-brake light sometimes stay on when the car is off.


I think that's everything.

I have searched google for hours on end to find someone with the same issues but haven't had much luck.
I have gone over everything I can without pulling the whole body harness out of the car.
I have replaced the time control module since all of these things seem to be controlled by it in some way but it didn't fix any of the problems.

Is there any way there is a connector or a ground or something somewhere that is common to all of these things?

Im just at a complete loss here.

Did you chew through the harness in the front left wheel well? Check underneath the dash on the drivers side, make sure the SMJ plug which connects the harness from the engine bay to the interior isn't loose.

These problems started before rubbing through the harness. Ill double check the SMJ.
