97 F-150 XL V6 4.2L Cruise control not working
It has a standard transmission, vacuum cruise control with no place or plug for brake release switch, no power windows/locks. I checked the vacuum lines and sealed them off, checked the fuses, and yet I still have no cruise. No indicator light shows when attempting to operate, and I have yet to find a replacement lever switch anywhere for it. Not sure if it is the switch or not.

If I am correct, the "Cruise" light wasn't added until late 99-00. My early 99 has no cruise light. Some models had the cruise cut-off on the bottom of the master cylinder, try there. As a quick check list: Does the horn work? Do your reverse lights work? Have you visually inspected the Clutch Position Sensor?

But yea, make sure you have the correct master/parts first. Otherwise, you don't have cruise....yet.
That might be correct, but they are wired for it. The OP must have the correct steering wheel. He would need the right master cylinder. The only other reason it wouldn't work is if it wasn't programed for cruise....doubt that's the case.

Yea, that's correct, deactivation switch is on the master. I'm not sure how the CPS integrates....seems like it would have to though. Not sure about that.

There is already a cruise control unit on the truck that is not operational. I have recently installed a servo as there were connections to install one, and I am going to replace the MC as well in hopes that this will give me CC again. Also, as to where I said lever switch, there are no buttons on the steering wheel, but instead a lever where the tilt would be.

Installed new master cylinder, brake release switch, and cruise servo with the cable. Still no cruise control. Does anyone know if I need to rewire the switch in the cab to the servo?

Everyone is forgetting the brake switch on the pedal. The wires break there or the brake light switch might be the culprit
