wired everything up and confirmed that the red with white stripe is indeed the fuel pump pin on this harness.

looks like red with white stripe is the fuel pump relay pin

Thanks for the info here guys you have def. given me some things to research! For reference this is what I have.... as you can see there is nothing black/pink where pin 18 would be

Hey guys, I had an R32 M/T RB20DET in my S13 quite a while ago, however I have replaced the chassis harness on the S13 and picked up a new motor (A31 A/T RB20DET according to the ECU) and I am having a hell of a time trying to figure out the dash wiring (specifically the black/pink wire for the fuel pump). It seems this A31 loom is quite different at the dash connector and there is not even a black/pink wire anywhere on the engine loom (on one of the 5 dash plugs that are there), or on the ECU for that matter. Every pinout I have seen is totally different from the actual wires on my ECU and i'm at a loss on how to wire this thing into my S13.... Any ideas? In summary : A31 A/T engine loom/ecu pinouts are different than any pinouts i have seen online (specifically around pin 18 Fuel Pump Relay)
