Hello everyone been a little since I've posted anything I'm trying to install a wiring harness from a 90 into my 65 but there is no fuel pump relay on the harness so need help figuring out where it connects to the pcm harness thanks

See post #9 in this thread. You need the complete wiring diagram eventually.

Electrical - Engine coolant temperature sensor

Which of the two pigtails plug into the engine coolant temperature sensor. One is the ETS and the other is canister purge solenoid. How can I tell the difference

The fuel pump relay on that year is mounted under the driver seat. If you want a harness with the fuel pump relay on it, you need one from a late 92 to 93., or you can wire in the relay to the 60 Pin connector on your 90 harness.

Is the fpr on its own harness or is it wrapped up into another bigger harness?

Click to expand...
he said it is not on the harness buddy. On the 92.5 to 93 there are two relays by the MAF plug- one for the WOT AC relay and one for the fuel pump relay. On prior years there is only 1 relay for the AC WOT. The fuel pump relay is under the driver seat.

91 to 92.5 harness is the first attachment
92.5-93 is the 2nd
3rd attachment shows where it is under the seat on 87-92.5 and on 92.5 to 93 by the MAF

Thanks @mikestang63, so wires for both fpr relays are integrated into their respective harnesses. So he has to find the relay wires for his year harness. I think I understand.
Maybe
Prolly not
Anyway, pay no attention to the idiot behind the kindle screen.
