What wire do I tap into to get a signal, when the vtec kicks in?
I wanna hook up a light that comes on when vtec is engaged.

Also how do I check the ecu for the code it throws when my check engine light comes on?

Thanks

 

Green/Yellow or (orange and white cant remember) wire connected to termanal A4 on the ECU. Run positive wire from a 12 VOLT LED light, to Pin A4 (which is on the bottom row, second from the front) Then ground the LED to any convienient ground. Only use real LED's, no light bulbs
