    I just got my d16z6 today for my 90 crx si. Ran into a little bit of a problem. The wiring harness doesn't plug in to the connectors near the fuse box. I'm planning on ghetto rigging the vtec using a fields afc vtec controller, a auto relay, and a rpm switch, but how do i plug the wiring harness into my ecu??? the plugs don't match!!! i'm confused. I could really use the help, i can't find it anywhere.
