how do i wire up v-tech for honda civic cx hatch
Re: how do i wire up v-tech for honda civic cx hatch (lil_sn1p3r)
You need to tap into the shock tower harness and then you wire them to the ecu harness. pin outs are A4 for the VTEC Solenoid, D3 VTEC Pressure Sensor and D3 for Knock Sensor GSR engines also need A20 EVAP Purge Solenoid, and A17 IAB Solenoid....hope that helps you out...... if you need anymore help email me at radyjr1@juno.com

When I wired my vtech, there were two wires. One was the phone wire that plugged into the jack in the wall. The other was the black power wire which I plugged into a power strip. Hope that helped.
