my Trans Am has a fried interior harness and a peiced back together engine harness. however, my car still run but some stuff does not work. i have always liked tpi for many reasons so i figure since im changin the interior harness why not switch to tpi. what else do i need to switch to tpi? besides the tpi setup. do i need the fuel lines too? if i used an external fuel pump how would i wire it up?
thanx

 

I would try to find a wrecked TPI car. You will need fuel lines, ecm, and fuel pump complex for in the tank. I would replace it with a walbro fuel pump. You will also need a fuel pump relay etc. If you find a donor car, just take the whole harness.

An alternitive wiring solution for the fuel pump would be the racetronix harness. Check out www.racetronix.com It comes with its own relays, etc.

 

thank man, thats wat i figured i was gonna have to do is buy a parts car. it is probably the best way to go.
thanks man
