Wiring Vtec into a Non-Vtec Teg
Sorry to bother everyone, but I'm helping a friend swap in a VTEC head into his LS and the one thing I don't know how to do is run the wire's for VTEC. He has a 97 LS which is OBD2 and he's gotten himself and OBD2 P-72 ECU. I know there are 3 wires you need to run in order for VTEC to work but to what pin assignments on the ECU do they go to. I would really appreciate any information. Thanx.

vtec solenoid=A8 
vtec pressure switch=C15
this is the side that the pins go into, oppoisite of the side that goes into the ecu. the other pin for the pressure switch can just be grounded to the chassis somewhere.
