I have a 93 DX coupe and next week i'm putting in a d16z6. I have found how to splice in the vtec wires to the p28 ecu, but I have seen rumors that my car has a plug in for the vtec in the engine bay and that they make a wiring harness that will plug straight from the vtec seleniod to this plug. Anyone know anything about this? Is this true or just "hear say"?
