hello folks I’m asking for a little help identifying 3 plugs on my engine harness. I’ve narrowed everything else down except the 3 displayed below. I haven’t been able to find a diagram for this specific harness, it’s similar to the diagrams provided on this site here but I have NOT found a match.

I pulled this harness from a 98 civic ex d16y8 engine, but I have reason to believe it once belonged to a 99 civic because of differences between a 98 harness. it has one gaint plug for the driver loom, NOT multiple, also evap purge control solenoid plug is in between the injector plugs.


left plug: 1 pin
blue/red

right plug: 3 pin
red/white
red/blue
brown/black




4pin
black/white
black/green
black/yellow
solid white

 

Knock sensor



CKF Sensor



Primary O2 sensor

 

Thank you sir very professional!
