gettin a b16a2 swap in my vx, do i need a wiring harness or do i already have the vtec wires?

 

You can use your harness and just add a few wires for knock sensor, etc. But vtec is already wired in

 

You car is pre wired with everything you need. See the instrictions in my sig. Don't worry about the secondary intake runner part. You don't have them.

 

As long as the motor and all the components on it are OBD1 then I would reuse your stock VX engine harness. If it's OBD2, like as in a 99-00 Si B16A2 with all OBD2 components then I would get a USDM OBD2 GSR/ITR harness. This will eliminate the need to change the injector clips, and the distributor and alternator plugs.
