strange black box under dash

Yes it is inded a cruse control.

Will need to have vaccuum to hold the throttle. Also check to make sure the switch for the brake pedal is set correctly.

Let us know if it still works.

Got a few things to do before I drive it again, but it is for the cruise control. Followed the wires from the stick down to that box.
Thanks for the help!

take the fuse out and see what quits working

Sure looks like a Cruise control box to me too.. I've installed a few (Not that make) but that's what it looks like.

Obsolete aftermarket cruise control box. Probably by Escort. ALL Class A motorhomes (Gas) until about 1990 had aftermarket cruise controls and once Ford and Chevy started installing their systems the originals went out of business and no parts available. YOUR system was an unusual system. It had a preset of 55 mph. Your turn signal lever should have a large black end that rotates and has a center "indent". When on the center indent and you push the engage button the system automatically is set at 55 mph ( this is programmable for other set speeds but was factory set at 55). To go lower or faster you rotated the black knob until it hit the speed you wanted. 1985 may have the magnets on the drive shaft for speed sensing. This was about the time they all went to speedometer cable sensors. Doug

Winner winner chicken dinner! That didn't even cross my mind to look for! Once I get it road worthy (for me to feel safe) I'll test it out and see if it still works, if not it's coming out haha

Do you have an aftermarket Cruise control? It looks like a control box for that. The after market cruise of that era had a magnet glued to the drive shaft and a pickup positioned less than 1/2 inch from the magnet with wires running from it into the cab somewhere. So look underneath for the magnet on the drive shaft, just behind the tranny.

Ohh thank you Scott.

352, I was wondering...where did you got your tinfoil hat from? :)

It is keeping track of everything you and your wife say.
