Before you all flame and tell me to search, I tried that and counldn't find the answer to my question or I didn't understand what I was reading.

I am doing an LS swap in my 89 iroc, in the begining I stupidly rippied out all of the stock wiring for the old TPI motor and sold it. My question is where dose the wiring from the fuel come into the engine bay at? While looking up something else I notice there are two pins in the C100 firewall connector lable as fuel..... are these the wire that I wire to the fuse box to power the fuel pump?

any help on this would be appreciated.

 

Don't own an F-body but remember that the fuel, pump relay was on the firewall, the one with orange wires, the fuel pump feed was tan with white stripe.

On the F-body TPI engine the ecm sends a ground signal to the relay, on the LT1, the PCM sends a 12v signal to the relay..not familiar with relay activation for the LS.

There must be a wiring schematic on-line somewhere?...if not send me a PM I might be able to find one.
