Cruise control year fitment

[f350CONVERSION]

I have a 1993 f350 4x4 crewcab 7.3 idi with turbo and the only option it does not have is a tilt column with cruise and the only trucks I can find locally are 94-97 powerstoke trucks I know the column will interchange but I was wanting to find out if the cruise electronics under the hood and dash will interchange? Thanks

column will interchange. the rest....not a chance. all ECM driven by the advent of the PSD.

You sure? Just from randomly looking at junkyard trucks it looks like gas & diesel 93+ (i think) seemed to share the same servo unit, which at least on the 93 unit I have has the computer built in. I know the engine is completely different, but cruise system seems to be a standalone system that takes input from the speedometer electronics.

Go to a ford dealer and ask them to give you other vehicles that you can get it from. I did it and had a printout that I can't find but it had pickups bronco's and vans up to around 97 IIRC also different part numbers. If you find them at a reasonable cost I'll buy one from you as I could not find one and I don't want to buy a new one because I'm not 100 percent sure that is my problem.

There is no servo on the PSD. There's nothing on a PSD that a servo could mechanically control. The accelerator pedal is just a big "volume control", a variable resistor. AKA pedal position sensor. It's not a "throttle" position sensor, it is, in effect, THE throttle. So the cruise control doesn't have to be any separate physical device the way it would on a gasser with a throttle, or an IDI with a mechanical IP. So when you set a speed on the cruise control, the PCM just tells the IDM and the injectors "give me enough power to maintain X speed".

Ah yes, idiot moment. Forgot how the PSD works.

One off a gasser may work though.

Depends on what it "pulls", I suppose, how it's connected to the throttle. They shoulda designed it like some cars, where the module/servo are inside, and operate on the cable from the pedal under the dash. That would make for a more universal application.

PSD is an odd duck.....
