I finally got my new ecu(p13) today and i was hooking up the vtec, i am using the stock h23 wiring harness to do so, i took the green/yellow vtec solenoid wire extending it and plug it in with the jdm plug, now i took the blue vtec oil pressure wire and did the same and i grounded the black wire. When I ground the black wire the tachometer quits and the vtec still doesn't work with the vtec solenoid and oil pressure plugged in,. Can anybody tell me what i did wrong.
