For the other, which just has the black wire, the best quick test is to measure the voltage on the ECM pin (A21-Pin 40) with the ignition on. If CC is active on the ECM, then that pin will have 12V on it.

well, when i opened up the D3 connector on my belta, i got these wires. Tell me what to do from here forward. SORRY about the blurry pic, was taken from my mobile cam. But the wire colors r pink, orange, grey and black. there is no blue and brown cable. How to check if my car has CC in ECM.
