I've been running around with no cruise for the longest time so I thought I'd get around to fixing it. The answer was very simple with help from GasGuzzler. Access the DRAC unit and cut the light blue wire with black stripe. Cut the red wire with white stripe. Take a butt connector and stick the two wires in one end and crimp. Take the speedometer signal wire from the PCM and crimp it to the other end. Job done.
BTW, the cruise control cable I used is from a 1998 C1500 with a Vortech V8.
PS, I had on here before to remove the DRAC box entirely but the brake system seems to use the DRAC module for testing.
