Sr20 no start

[Xxs13240xX]

So I bought a friends friends s14 brought it home yesterday everything was running smooth after we got the tires to not rub in the front
Anywho today I head out to school and on my way back it starts acting odd it would act like it just shut off the key and then i started it back up and it was fine then once more it stalled out just this time i couldn't get it to start back up the negative battery terminal connector was bad went and replaced that. Drove fine shut it off started it back up was perfect then last but not least I was on my way to work and the car shut off right in the intersection couldn't get it to start tried jump starting it then tried bump starting it nothing.

Symptons are now:
All dash lights will stay on even when key is out of ignition
Car's reverse lights work even when key is out of ignition
ECU relay buzzing at random times when I try starting it then it stays buzzing

Things I've tried:
I've 95% of the fuses under the dash and every fuse under the hood
I've checked the grounds even added a new one where I thought it could use one since the old one was going bad.
Swapped out relays from under hood to the ecu still nothing

I'm quite stumped on this right now basically everything is electronically stock besides the MINES TUNE ECU... Help me out I miss it already

Oh also this car was running perfectly fine for the time that he had it and then yesterday the ground terminal connector was bad so I replaced that and this is all that's its doing now

Your tires were rubbing? Did you check. The harness in the driver side fender well?

[Xxs13240xX]

Yes tires wererubbing because of the wrong offset rims and no didn't check that part of the harness

[OutToWinPAHC]

Yeah sounds like harness rub through.

[Xxs13240xX]

Rubbed through the harness gonna clean up the wires and seal em up I'll keep you guys posted

[Xxs13240xX]

That was the problem... Problem solved Thanks NICO

[Xxs13240xX]

Got it running it was the wires from under the left front fender but the lights on the gauge cluster still stay on as long as I unplug the negative terminal when I shut it off it'll be good unless you guys may have an option

[compactfean]

Start doing some testing. Get a wiring diagram, figure out which wire illuminates the cluster. (S13 is. Blue wire) and see where it goes...combo switch? Maybe dimmer. Switch?

Will do anyone know the best spot to get a wiring diagram?
