i am new to this whole vtec thing as i have just finished up putting my Z6 in my EF hatch yesterday all by myself... my question is what makes the vtec solenoid engage... a buddy of mine told me that there are two wires... one from a 12v source and one ground... he also told me that the ground is what is used to turn the vtec on and off... i looked at my motor today and there are 3 wires... a lone black wire on one plug and i believe a black/blue wire and a black/yellow wire on the other... which one is which and how do they control the vtec solenoid? thanks a lot for the info
