Hello, I am new to this forum. My name is Larry. I have a 1984 shasta motorhome on a chevy g30 chassis and a 350 sbc. There is a Travel Accessories Inc cruise control servo hooked to the carb that is attached to the frame next to the trany. It is not wired. I need a wiring diagram so I can get the cruise working. I cannot find any info on line relating to the travel accessories unit. I do not know if any other part of the cruise control is travel accessories or standard chevy product or an aftermarket. If anyone can help me I will be very thankful.
Thank you in advance for your assistance.

 

this post has some useful info.

Schematic for "Travel Accessories" cruise control

 

You may be better off buying a modern electronic cruise control from Rostra instead of piecing together a 40 year old set up. Easy to install and controls that look like a factory setup.

 

Will a modern one work with a cable speedometer?

 

The Rostra has two different ways to measure vehicle speed. One is with magnets on the driveshaft, the other is a a small generator that goes between the speedometer cable and the transmission. It then outputs a signal to the speed controller. Much more reliable than magnets IMHO.
