Quick question about the SR5 oil pressure sending unit
So I have the SR5 oil sending unit on the side of my motor.
I am looking at the ECU pinout for the 22re and I don't see anything labeled on it for the oil pressure gauge. Does anyone know or able to tell me which wire that comes down from the intake manifold should connect to this sender?
Thanks!

there's only a few single wires coming out of the harness. if you can narrow it down to a couple , with ignition switch to on: ground the right wire and your gauge will peg to the top. no ECU pin.

Generally not a good idea to short the wires to the analog gauge (OK with the idiot light). Why? The gauge works by putting a known voltage across the sender resistance and registering the resulting current on the gauge (Ohm's law: I = V/R). Problem is when you short the connector pins, R=0 and things go boom!
