I'm just doing the finishing touches on my 91 formula. (info in sig) Can I scrap the computer and all the wiring, I saved a majority of it and stashed it away for now. I'm running a holley 650 dp w/ a converted points dizzy. I hardwired my fuel pump to the relay, it turns on when the key is on. So, can I get rid of the wiring and comp?

 

Take it out and sell it on here



In other words, you can take it out.

 

is it possible to leave the computer in there just so it can control tc look-up and the fuel pump?

 

No.
Yes.

 

ok so if i took the computer out, what would be the best way to control these things?

 

TCC: 1) a kit from Summit, Jegs, TCI, etc., or; 2) a normally-open pressure switch on the 4th gear port in series with a vacuum switch, or; 3) a driver-activated toggle switch in series with a vacuum switch. In all of these cases, the power would still go through the brake switch - these other things just complete the path to ground. Details can be found on the Transmission forum.

Fuel pump: Wire a switched circuit through the oil pressure switch. For priming purposes (although not pure), a parallel power path to the starter solenoid. If you're clever, through the timed relay.

 

I wired mine through the OPS. I have a manual so no TC for me. I was hoping to just scrap all the wiring and comp. What about my radio or fuse box or VATS? I don't have ac or heat.

 

wow i didn't really understand any of that. is there a website that goes step by step with pictures? lol.

 

The radio and fuse box are independent of the computer. There's a tech article about VATS linked from the thirdgen.org homepage that has all you need to know about it.

 

I used a toggle switch and a fuse for my fuel lpump and provided a new power line. I had to put to of the factory wires together on the rear part of the harness I used. Its been a couple of years and I belive there was a grey wire that was hot...I left my fuse box as all my lights and ACC work...
all the computer wiring harness where removed.

later
and
