If the Belta has blue and brown as the other two wires in D3, then it should work. If it has the cruise control indicator in the cluster, then to test it just jump the blue to the brown with the ignition on and the CC indicator should light.


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.
