so i just swapped a B17 to my 1993 delsol. i swapped out the old PO6 ECU for my P30 ECU but the vtec isnt working. the vtec silinoid (not spelled right) isnt hooked into the engine wiring harness for some reason so i have it wired in right at the ECU. the wire colors i have it hooked up to is a orange/white one, orange/blue one, and a brown/black one (i think its a ground) im not exactly sure how the wiring on vtec works but im pretty sure one is a temp. sensor, ones a oil pressure sensor and the final one is a power that goes to the vtec silinoid? im just lost as to why the vtec doesnt work. i had the engine and ecu in my other delsol but it was a 94, that wouldnt make a diffrence would it? same OBD isnt it? Also i have it hooked up the same way as it was in the other car when the VTEC DID work. so is there any advice you guys/gals could give me to help me figure this out?
