Alright, I must be worse off than an Idoit, because I can't get this wiring figured out.

Well, just one piece of it really, the fuel pump relay

Swapping the LT1 from a 95 Z28 into a 91 Z28. Problem is, I don't have the stock harness for the car. I picked up a spare bulk head connector (C100) from a 91/92 firebird, but it has a really short pigtail on it. I have the fuel pump relay with it, but it is only connected to the gray wire coming out of the bulkhead connector. I have no other wires going anywhere.

So can anyone give me a clue? I have the guages, power, charging and switched wires figured out. I'm just when it comes to this relay and how it wires into the car.

Alright, I'll go back to beating my head against the wall

thanks

The thing I'm doing is using my old relay which has orange, green/white, black and red and wiring the green/white wire out of the new PCM into it so the relay gets the fuel signal from the PCM and then wiring it up to the existing wiring running down the drivers side to the fuel pump

Thanks for the diagram

Looks like I'll need to find a harness and go from there..... *ugh*

 

You don't need a harness, you can do one of two things... get a 4 pole relay that is the same value and wire it in, or find a 93-97 LT1 car and get the relay from the driver side kick panel.

 

I have the thirdgen fuel pump relay, but no wiring under the hood other than the C100 connector with maybe 12" of wire hanging out of it....... Just don't know where the rest of the relay wires go

I printed out the wiring diagrams, I'll try to look at it on monday night when I have some free time

Do you know how a relay works? A picture of what your working with would help me help you.
