Fox body won't shut off!!!help
 

I am no wiring guru but attempted at wiring the psi harness. Here's the deal , wired it had it running and could shut the car off. Well I decided to clean the wires from just laying across my floor of my car and now it will start and run but won't shut off... Help me

My first guess without more info is that you have an ignition feed hooked to Constant 12v

I'll double check tomorrow but I messed with it a bit today and my fuel pump is wired to switched if I'm not mistaken and I tried to wire the ignition to that and same thing happened.

Check the 2 black wires that hook up from the psi harness to the starter.

Sounds like your alternator feed wire and ignition wire are on the same wire, so the alternator feeds the system and keeps it running

This is in no way helpful, but it reminded me of a friend who was driving his 11 Silverado when it got hit by lightning. It wouldn't shut off either.

Psi harness is stupid simple, just follow the manual that came with the kit.
Its like one wire to a switched power source and a couple of grounds. Everything is all wired nicely to relays that you dont need to mess with...

Got a add a circuit , car now will shut off!!!!

It's not that easy, especially if you have no electrical experience at all. But yes it is not terribly hard to figure out
