My situation: I had my EG stolen a few months ago, and am still working out the bugs in the motor that these thieves have caused. My motor (JDM SOHC ZC) is running very strong, I can easily keep up with my friends LS (JDM B18B) w/ Type R Trans (LSD). I noticed however that my Vtec isn't engaging; I've assumed this is because my O2 sensor wiring has been cut and it is not throwing a code, disabling Vtec!? I've read the wiring diagram, and this is what I can tell the pinout will be; can you concur?

Black O2 - Yellow/black (Injectors) (A13 and B1)
Black O2 - Orange/Black (A16)
Green O2 - Green/White (D22)
White O2 - Orange/Blue (D18)

Also, while viewing the pinout, I noticed the yellow/black wire goes through all the injectors, Evap Purge Solenoid, and the A13/B1 pins; should I just splice into once of the Yellow/Black wires, or directly connect it to A13 and B1?

Finally, how do I know which Black is which???

Any help and wiring techniques/theory, would be appreciated. Please note, I only have worked on wiring which requires "Current (12v and grounds)" not really signals (ECU/ECM's).

 

Bump

 

All of the Yel/Blk's go to the same place, which is sourced from A25 -- which is the sensor positive pinout.

They all run to a Yel/Blk junction harness on the driver side passenger harness with a circuit plug plugged into it.

As for the blacks, it doesn't matter. It's the voltage sources, needed with a ground & sensor power. That's about it.

good luck.

Any more thoughts before I do this???

 

Not a one???
