Gday all,

Looking for some information about a K20A Engine Harness off an AUDM DC5R.

First question is, are there two harnesses or one? There's one underneath the intake manifold which goes to the fuse box and obviously the main harness which goes to the ECU. Are both harnesses relevant to K-Swap, or just the main harness?

Also, the harness I have has a green and yellow wire exposed and no connector on it and I am trying to figure out what it is for. Hence, I'm trying to find a wiring diagram for the Engine Harness.

I"ll try get photos up when I can of the harness and general location of the plug.

Just by laying out the harness, my suspicions is that it may be one of the cam sensors.

Exposed wire is at the bottom. On second though may not be cam sensors but very close as I think the two blue plugs at the bottom are it.

Could be the ECT wires.

Answers are:
1:This part of the harness is the charging system (alternator), starter & knock sensor.
You'll need it if you're using an OEM harness.
2: ECU coolant temp sensor.

One final question. Any idea where to get one of the plugs? Or perhaps does anyone have an image of the connector? Maybe I can get one off a different harness and rewire it on...?

Can use it off other k-series motors. EURO/ACCORD and etc.

Bump, further investigation shows it is actually the reverse lockout switch! Now to actually source one..
