Can you use a H23 harness on a H22a engine ?? ECU = H22a ??

yeah the engine harness is fine, but you will have to run 2 extra wires, one for the vtec pressure switch, and the other for vtec solenoid - a4, and d6. it's much easier than chucking in a whole new harness. ecu = p13.

the red search button is also your friend.

 

Yes the Si's are actually wired for VTEC from the factory. There is a spot to plug the wires into by the fuse box under the hood. I would recommend just running the wires straight to the ECU though.

 

not all are prewired. but yes you can use the h23 harness on an h22a engine. just need the vtec plugs and wires.
