more harness/sensor issues

[civicious]

aiite, i think im about finished with my wiring harness issues.

i ordered a harness from a 99 DX, which im hoping will plug into my obd2b si ecu.


i konw i'll have to add wires for the vtec and the knock sensor.


my question:

on the back of my obd0 block, there's 2 sensors. one has one prong and the other has two. i remember on the obd0 harness, the 1-prong sensor wire was yellow/red.

which one of these is the knock sensor, and whats the other one?


also, how do i add the wires for the knock sensor/vtec? i.e. where do i hook the wires to?

:unsure:

help please?

If the ECU is a PR3, then this site should help you out.

First there should be three sensors back there.

The sensor with one prong is your oil pressure sensor. The one with two u leave unplugged. The knock sensor is the highest up up and it has a one wire plug similar to the one on your vtec oil pressure sensor.

I'm not sure what the pinouts are on an obd2 ecu.
