I am doing the above swap and of course the wiring harness is different.

There is an extra plug near the ECU.

There is one less plug near the U-shaped fuse box.

There is of course the plug to activate the VTEC solenoid.

The layout of the fuse box is different.

I am contemplating swapping the harness but that is a hell of a job.

Is there an easier way out of this?

Appreciate any help.

 

i dont know what harness you have but it should be a plug and play. I have the same swap in my DA, and everything plugs up. you have to run 3 wires. a wire from the vtec sylanoid to the ecu, the vtec oil pressure to the ecu, and the knock sensor to the ecu. you can tap the two o2 sensors to make one wire. hope that helps.
