VTec wiring question
I have added a Y8 head to a d15 block. 92/94 Civic which is a gutted caged oval track car that was butchered long before I got it. Have the p28 ECU. If my info is right, Vtec goes to A4 pin and pressure switch goes to D6.
Question is, which wire is the ground and which is the live from the pressure switch,......ORANGE/BLACK, which is on the side with the clip release nearest firwall or, BLUE/BLACK which is block side of the plug??
I got the plugs from the only unmolested vtec harness in the junk yard.

Re: VTec wiring question
Your Blue/Black is your ground. Run a ground wire to your T-stat Bolt where your ECU ground is, so you're not running 10 ft of wire. Run the other wire to Pin A4.
