Another F53 Cruise Control Post - Help!!
Hi Everyone! New to the Forum and new to Rv'ing! Just purchased a 2004 Holiday Rambler 30PDD and absolutely love the thing, except for one thing. The cruise control does not work. I know, I kn...

Ford stopped using vacuum operated cruise control awhile ago. If you do not have an electronic throttle body (throttle-by-wire) you probably have a standalone cruise control module.
First, is there 2 cables going to the throttle ? If yes, one is for the accelerator pedal and the other goes to the cruise control servo. It should look something like this.
The "smarts" are usually in a separate metal housed boxed mounted on the the left hand inner fender.
I could not find a wiring diagram for an F53 chassis, but I did find one for an E450. On the cruise control servo, pin 7 Hot in Run. Pin 4 is Hot At All Time when the brake pedal is depressed. Pin 9 is Hot In Run when the the brake pedal is NOT depressed. Pin 10 is ground.
Likely one of these 2 is bad. They are not expensive in junk yards.
There is a third "shot in the dark". Around that time, Ford had an issue with fires caused by the brake pressure switch. This switch was a backup to the brake pedal switch (if both tail lights were not functioning, the CC could not tell you had stepped on the brake except for this backup). The "field service" fix was to install a short jumper with an inline fuse going to this brake pressure switch mounted under the master cylinder.
