hey there. I've got a question regarding the plug shown below. I think i've got everything figured out with my lower harness. Except for a couple things. The plug in my hand plugs in by the fuse box, and goes to: (1. 5th gear sensor (yellow/green wire), 2. Not sure....i think it was part of the EGR system on my KA24E (black and red wires), and 3. Power steering sensor (orange wire))

Since the RB doesn't have a 5th gear sensor, and i don't think i need the other plug, can i just eliminate this plug from the entire harness? I'm also running a new Hi pressure line that eliminates the sensor.

I have: Neutral, Reverse, Alternator, Starter, and VSS. this should be it....correct?

hmmm.....anyone?

basically all i need to know is what function the black & red/blue wires serve. As i recall they're part of the EGR....but there are about 3 identical plugs on the lower harness so it's kinda hard to tell.

The black & red/blue wires are indeed for the EGR system
