Does anyone know what the little silver box and relay looking deal right behind the passenger headlight is? ive swapped my turbo motor into an n/a and im running harness........i dont see a plug for it on the driver side n/a harness....i know the swap can be done without changing the harness, so what do i do?? do i need it??

If it's what i'm thinking it's either the fuel pump relay. or the relay for your fuel injectors. I would think you need it. But i would keep asking.

I know what you're talking about, but don't know what it is. I know it is not the fuel pump relay, that is by the fire wall on the drivers side.

its the fuel pump resitor and resistor relay

no, you can hook the fuel pump up to a 12v ignition source too

um, i dont have it hooked up and my fuel pump comes on when i turn key on, i dont think it goes to fuel pump....

it regulates voltage to the fuel pump. well the middle resistor does. I think it's the white wire. Anyway i wouldn't use it. I don't now, but that's because i have a haltech.

ok, i know what it is, it is the thing that makes the injectors run at high impedence....what happens if i remove it??
