Im looking for the fuel pump relay (havent looked too hard) for a 91 Z, was originally a tpi car and im swapping in a lsx. I completely eliminated the stock engine harness, im not sure if it was on it or not but I havent been able to find it. Im using a stand alone harness so I bascially just need it for the wire to the pump. Thanks

 

On my 91' bird it was on the fire wall, driversside at the top behind the master cylinder... might be the same for yours????

 

Or enter your car at autozones website and they have a section that will give you componant location for different parts on your year/make car...

 

The autozone just tells you the general location. It's really here:

There's two behind the bracket, I think it's the one on the left, IIRC. It has a gray wire going to it.
In case it's unclear, it's like actually on the firewall.

 

Thats all gone, I sold that with the engine. Now I just need to find where it goes to the tank. I know its not at the bulkhead at the firewall so it must be in the connectors where the original pcm was.
