VAFC on PR3 (VTM signal)?
 

HI, All I just installed my VAFC. I am looking through the instructions now. I was wondering where to install this wire? I am looking for the pinout letter and #. I read that some don't use this wire. Is the PR3 one of them? TIA

VTM is just the oil pressure switch next to the solenoid. Basically just cut the VTM wire as it comes out of the ECU, and attach it to the VTW wire to the VAFC. The VTW wire is definatly in the diagram. If it isnt, just download the newer manual from apexis website.

If you plan on raising the vtec X-over above stock, then its true that you dont have to hook it up. If you lower the X-over below stock, you will need it or you risk losing a few HP.
