B16 motor swap on 90 integra?

I just got done putting a ls vtec in my 90 integra and on the pgm, there is olny a place to plug in one or the other..





Either the regulator control solenoid valvle or the purge cut solenoid valve, the are the little black things next to the map censor, the regulator is the one on the passenger side and of course the purge is on the driver side, does anybody know what one i wanna plug into the fuel manifold, or do i wanna just splice them together, i have the regulator pluged in right know the car seems to run fine, but is that correct?
