Searched but can't find it because search function does not pick up "1", "4" and "o2" so.....if anyone has a link....and i don't want to rewire back to the ecu....it can all be done in the engine bay...just can't find the link....

thanks

If you can, just use an engine harness that uses a 4-wire o2 like a dx, lx, ex, or si. If you have a 92 you should be good to go after that, if not I think you have to go from the shock tower back to the ECU. Anyways, if this helps...

WHT wire goes to D14 which is O2 Sensor Input (needs to be a shielded wire with ground)
BLK wire goes to A6 which is Heater Control
GRN wire goes to D22 which is Sensor Ground
BLK wire goes to B1 or A25 which is Sensor volta

Also be sure to use a 4-wire o2 sensor as well

For further reading try searching for "wire sensor" in the archives.

 

I think my o2 is wired that way.

 

hey, have you heard of this

VX O2 sensor fix:
If you have a VX model Civic, and you do NOT use the VX engine harness, in order for your O2 sensor to properly work, you need to move the ORG/BLU wire from the 4th connector at the shock tower harness, and move it matching with the WHT wire on the 4 wire embedded engine harness
