What is this plug?

Post by **cvc9216** » Sun Mar 28, 2004 2:00 pm

I'm starting the wiring for my rb25. I can't remember where this connector goes on the rb25 transmission harness, I just want to know if I need it. It comes out near the alternator, two wires, pink and black. I know the pink wire goes to the plug near the *edit* fuse box. I don't see a connection for it on the engine and I can't remember where it goes. Also, in the grey plug on the bottom right of this picture, anyone know what the grey and black/white wires are for?

That bottom pic looks like the plug for the crank angle sensor and second O2 sensor that comes from the lower harness and connects to the upper harness and ECU. But which engine is this for? Is this the KA lower harness or the RB lower harness?

I left that one unpluged cause it didn't go anywhere.

This is the RB harness, the grey plug is the one that goes to the upper harness near the throttle body. It has the knock sensors and the IAC (or whatever that blue plug is), but I can't figure out what the other two wires are

so I'm assuming I can get rid of that red connector? anyone know what it's for?

ok, I figured out what the two wires in that grey plug are for. If anyone can tell me what that red plug is for it would be a huge help. I'd like to get the transmission harness done tomorrow so I can start working on the engine harness. TIA

I have no idea what it is for but I know my car run just fine without it.

ok, I'll probably just get rid of it then. It would make me feel better if I knew what it was actually for though

It may be the power steer idle-up.. its not needed

Power steering pressure switch comes in through F3 if you want to connect it. It's not hard.

ok, that's exactly what it is. I didn't notice the RB has an extra sensor on the p/s rack, in addition to the pressure sensor on the hose. great, now I can finish the transmission harness thanks
