Here's the pics I got, 1st one is the plugs that sit next to the battery, 2nd one is the plug on the RB20 harness.

Thanks, Ryan

 

2nd pic RB20 plug.

 

I believe that the red plug ont he car has the fuel pump wiwirng that should go to the ECU and the grey one right next to it has the switched power wires...the RB plug is the one that the switched power wires go to, if I remember right....there should be a black/red and possibly a solid red in the RB harness that would go to the matching wires in the gre KA plug. The black/pink wire in the redish plug goes directly to the black/pink wire on the ECU for the fuel pump relay ground.

 

Here's the colors I found on each plug.

small red, the only wire that matters is black/pink

I am gonna have to look at my RB20 pinout I made and see what colors from that grey plug go to the red/black and red wires fromt he grey plug...later today I will figure it out for you.

 

I got it, went down to another shop that had a RB20 clip and tested the wires. 3 were constant +, one was switched +, 2 don't do anything and match up to the ECU pinout as A/C switch and P/S sensor.

 

the AC switch dont really worry about, the PS sensor you COULD wire up if you want, but the RB motors can handle the power steering no problem...

 

what does this do, the PS sensor? I also have a Hikas P/S pump can that one be tortured to work?

 

you gotta plug the rear rack holes, but it will work.

The PS sensor tells the motor to idle up when it senses pressure in the power steering system...kinda helps the motor not to stumble when turning at a stand still.

The RB motor can handle it just fine though.

 

I heard you have to connect them somehow. A guy tried plugging his off on a SR swap and it leaked all over and then the pump burned up. Thanks about the steering sender I will probably hook that up, but it's not anything vital at least. I'm still waiting for the water pump

 

I saw a couple installs where they just got threaded plugs and snugged them down, no more problems.
