Hello, four a few months now i have had my b16a swaped into my 89 crx dx. Ever since i got the motor in there i havent been able to get vtec working. (IACV code and Knock code) So i went crazy and ripped ever peice of wire protector on my entire harness off and found that there was a black wire not conneted to my knock sensor, just and orange wire. Im not a big wiring person so i need to know if that black (i Guess ground) wire goes there and were i can get a pin to go into the sensor connection so i can attach the wire. I got the vtec harness from hasport, i dont understand why they had that wire hidden........those bastards.

As for my idle air valve, i have replaced the unit and checked the ecu and it appears the right color is in the right spot.. if you can help that would be great.
thank you, Travis
