    ok i have a 91 civic si hatch. i bought it with no motor installed. but it came with a JDM b16a sirII motor. it used to have a sohc d series in it from a 95 civic ex. so it is already obd1 wired and has a p72 ecu in it right now. ive been looking at the pinouts and it seems some of the colors of my wires are wrong. apparently a4 is supposed to be the VTEC solenoid wire. and its supposed to be green and yellow. mine is orange and white with silver dashes. weird? can someone show me where the vtec wire is on the shock tower plug?

    and is it possible that someone just hacked the wiring and used the wrong color wires?
