Yesterday I bought the P08 I've had my eye on.My cars a 93 civic DX so it didn't come stock with vtec but I have a D15B vtec in it.So I need help running vtec.

What I want to know is:
Does anyone have a wiring diagram for the P08 ecu?
Do I have to do anything special before installing the ecu?
Will I have to get the pins for the ecu harness or are the pins already there?

 

You only need to concern yourself with 2 pins, vtec solenoid and vtec pressure switch, the rest doesn't apply to you. You will need to get 2 pins for the ECU. You might be able to get the from honda or go to a junkyard and depin two wires and cut off about a foot wire on each one so you can splice them.

 

Great diagram,thanks.So the A4 pin goes to the green/yellow vtec solenoid wire and the vtec pressure switch has a black and blue/black wire running from it...don't I have to hook up both of those wires?

Yes, the blue wire goes to pin D6 and the black wire is a ground. green/yellow as you said goes to pin A4, you can thank katman for the diagram.

 

Ok so then I just ground the black wire to the frame.Thanks for the help
