First check for power at the cruise control switch with vehicle running. Diagram below. Turn cruise switch on and check for power on the pink/black wire. This is power going in from ignition switch. With switch on you should have power on the gray wire also, this is power going to the brake switch and PCM (Cruise on/off input, Pin D2 at PCM). Check these first and let us know what you find.
