ok problem here, hybrid garage gives a guide to hook up vtec into a non-vtec civic, but problem here. I need to know what to do if the space for the vtec solenoid is already taken by another wire. In other words, a4 is supposed to be the vtec solenoid, but in my case, i have a 94 honda civic and on the harness, that spot is already filled, what do i do?? some one chime in with some helpful FACTS.

 

If A4 is already there, then that means your car was wired up for VTEC already. That spot is only reserved for VTEC according to my wiring diagram.

 

i found my own problem, i was reading the plug backwards.

 

I have a 94 CIVIC and i put a 1.6 v-tech head on my 1.5 block how do i make the v-tech work?

 

You'll need a P28 ecu and do some wiring.

 

Dont forget to get the vtec solenoid plugs as well, they help alot. and i know the vtec pins are a4 and d6
