    Ok so I have a 1994 prelude Si. Had h23a1. I just put in a h22a4 and got a chipped p13 off ebay and I Wana wire my vtec. Only problem is my solenoid doesn't have a vtec oil pressure switch for some reason. I was told you can bypass this by putting D6 to A4 but will this make my vtec engage? Or do I still need to hook up the green w/ yellow stripe wire on solenoid to something?
