i just swaped to a z6 motor. im using the dx harness and want to wire up for vtec. on the vtec oil pressure switch which one is the ground(black) and the hot wire(? color).

i guess im trying to say is the wire closest to the distributor is it the ground or positive? so i can run it to the ecu harness and ground the other wire. the solenoid is only one wire so im good on that. thanks

 

run the blue wire to pin D6, and then run the black ground wire from the plug to a good ground. then run the green wire from the VTEC solenoid to A4.

 

thing is i dont have the plugs that hook up to the oil pressure. so im going to custom make a plug, but i need is some one with a z6 head to tell me if the wire on that plug that is closest to to dizzy is the ground or the hot wire.
