can anyone show me a diagram or explain which of the 3 vtec wires,red,black,blue i believe...which wire plugs up to which connector next to the distributor?thanks

 

what year is the car, motor or what kindna harness are you using?

 

93 civic hatch,b16, harness?

 

anyone?

 

well those wires are close, but not close enough. if you have a meter then you can use it to ohm those wires and use it.
vtec soleniod = grn/yel = a4 at the ecu
vtec pressure switch = blu/blk = d6 at the ecu. the blk will go to ground.

 

thanks man

 

if your motor does not have a pressure switch, you can run the ecu wire for the switch to a ground. Just FYI.

It is better to get a pressure switch in the long term, but this will get VTEC working. Quite a few newer JDM motors didn't come from the factory w/ a pressure switch for whatever reason.

 

cool thanks
