Hey guys I will be starting my wiring very soon so I need everyones help. Below is a gay diagram I drew up in paint of the engine harness. As you can see, I did not know what some of the plugs were. If anyone can help me label those I would greatly appreciate it. Also since the SII RB25 has two plugs to the throttlebody, I wasn't which one of the two was the tps, if anyone could clear that one up it would be great. And finally I want to remove all unnecessary plugs from the harness, can anyone tell me which plugs and wires can be removed?

Off the top of my head- (don't know for sure about series 2)Close to the ecu, there should be a large bundle of wires. That would be the "white plug" according to the 8 step. That pretty much gives your instrument cluster the signals and also some ignition wires.

The other bundle should only consist of 4 wires which hooks up to another relay. One relay is for eccs and the other ign.

That is for the series 1 and I am not sure about series 2. Hope that helps some.

Red plug is for the variable cam timing solenoid...looking into the others.
