I have a 99 Civic DX HB. I am putting in a GSR motor soon so I bought a 99 Civic Si engine harness off someone here so I didn't ahve to deal with the wiring. One of the plugs isn't on my stock harness so I dont know what it goes to. It looks like the typical Honda 2-wire plug but with only one wire and it is red/blue. It is close to the plug for power steering Here is a pic:


I also wanted to see if someone could verify the colors of the IACV plug and the 2-wire plug for VTEC Pressure Switch. Thanks a lot.

the red/blue looks like it's for the knock sensor, but i'm not sure if obd2 harnesses have knock sensors.

VTEC Solenoid Yellow/Green A4
VTEC Oil Pressure Sensor Blue (passenger side harness) D6
VTEC Ground Black chassis ground
Knock Sensor Red/Blue D3
Evap Purge Power Yellow/Black 12V power (hot in ON or START)
Evap Purge Solenoid Red A20

Black/Blue (B23) and yellow/black (sensor voltage)

VTP:
Blue/black (c10)
Black, ground

Those are OBD2b ECU pinouts

Kabir/shawn, if you need the wiring diagram, I will sent it to you.


The others were right about the knock sensor.

Those are OBD1 pinouts. IF you convert to OBD1, you can use that info.
