hey fitting vtec controller, am sure this has come across here many times, but cant fine it, i want to know which wire from the ecu is the vtc signal wire and tdc signal wire. any help? plz

also i tried apexi and they dont give u a pin out of the vtc wire and tdc wire.

thanks

 

Nah... '79 Civic didn't have VTEC. In fact, it didn't even have a tdc sensor. Just breaker points in the distributor.

Maybe you could tell us what year/model you have?
