Hi.. I'm New here to the site. well let me get straight to my question. I have a 1994 Civic Hatchback and I have just swapped a D15b SOHC Vtec and i have the p28 hooked up to it . Since i used the factory wire harness that was on the car, my vtec isn't working because it isn't hooked up. Well i have been told that i could run two wires from the ecu to the vtec directly. I need to know the color of those 2 wires. The ecu is a p28. Thank You.
