How does cruise control work on a manual, carbureted vehicle and is there any way to add cruise to a truck that's never had it? If I could add it, the controls would be mounted on the dash, NOT THE STEERING WHEEL.
Would the cruise parts out of a junkyard 84 or 85 Mustang work on an 86 F250 Straight 6?
My friend has a 84 4X4, with a manual tranny, that has a 351C engine (we think) and it has cruise on it. Do you want the cruise parts? We are going to start stripping the body off next week. I'm sure that he want to sell the chassis, and all the running gear/ suspension stuff. The cruise disengages when the clutch pedal is pushed in (so the engine doesn't over-rev), other than that it works the same as an automatic tranny. Send me an email at garykipfer@aol.com if you want the cruise parts.
The hardest part is the speed sensor. The older vehicles with no computers used a special set of speedometer cables. They used a short one going from the transmission to about the steering column area under the hood, where a speed sensor thing screws into the cable. Then another short cable screws into the other side of the speed sensor and continues on through the firewall into the speedometer.
After that it's just mounting the servo, mounting the brackets under the dash for the vacuum dump valve, and the wiring. You have to be able to read and interpret a wiring diagram. If you can't, it's not going to happen.
They are hard to find and not cheap, but they still make aftermarket systems you can add on also.
