I have an 87 Camaro that had an L98 in it that is being replaced by a built carbed engine. I want to run the in tank fuel pump that supplied the L98 as it was just replaced with a high performance pump. I will be using the Mallory 4309 afpr. I want to keep the fuel pump relay and oil/fuel pump switch wired in to protect the pump. I no longer have the ECM, but plan to wire the relay as follows:

TAN/WHT wire from relay to fuel pump switch.

BLK/WHT wire from relay to engine ground.

DK GRN/WHT wire from relay to +12v ignition source.

Small ORN wire from relay to B terminal of IP Harness (shouldn't have to worry about cutting this wire).

Large ORN wire from relay to fuel pump switch.

I know that the DK GRN/WHT wire from the relay runs to the ECM connector and is used to energize the coil in the relay for 2 sec with the key on, and supplies +12V to the coil in the relay while the engine is running.

Does anyone know if this wiring will work, if not can someone offer info on the correct way to wire the fuel pump relay without an ECM involved?

Thanks in advance.

 

The only wires you should have to alter are the black/white and the dark green/white in the manner you described. The rest of the witing can remain intact, as the factory wired it:

 

Thanks Vader, that diagram helps out a bunch. It looks like if I unplug the computer, but leave the harness intact I can make the wiring modifications you suggested and my fuel pump will work fine. Is this correct?
