I'm going to need to wire up vtec in my car and change it from a 1 wire o2 to a 4 wire. My question is are all the slots in the connector that plugs into the ecu full, with each having a ecu pin in it, wether or not something is ran to it? If not than does anyone know where i can get the pins for the ecu ? My car was made in 92, but the title says it's a 1993, but i think that it has a orange wire with a blue strip on it that goes to the shock tower harness. Is that the Vtec sloenoid wire ? If so should there be another one there for the Vtec oil pressure switch, if so what color should that one be ? Thanks.

 

no there will be an open slot for the v-tec wire in the ecu. There are no pins sitting in the empty slots. If your good with wiring, you can open the harness and wire it in. If your not I'd go buy a pin (honda dealership) so you can just slide it in or assuming that you have the OBD2 harness that came with the motor, fish out the vtec wire and use it.
