OK, I'm back... Finally decided to look into the cruise control today after I welded new supports for my battery tray (rusting away). Right off the bat, I noticed its plumbed wrong. The cruise actuator is under the master cylinder on the firewall, and everything moves freely by hand, but it has 2 vacuum lines, and I know its not right. Both of them go to a little tin can on the firewall... and nothing else is plumbed to it.
How does this hook up? I'm guessing the canister has a check valve in it (if not, I'll get a universal one), but where in the system is this routed? Why 2 vacuum lines to the actuator?
Its a 1980 Winnebago Minnie Winnie on a 1979 chassis... what I thought was a CB300, but I found a sticker in the cabin that this little 20.5 foot unit is actually an MB400, probably because it was ordered with the 10,500 chassis.
On mine, which still has the original, functioning cruise control, the actuator is located on the rear, of the driver's side of the engine. I don't know what year Dodge changed it -I suspect it was probably 1978, when the body style changed slightly - but on a 1983 B150 I found in the junkyard, the actuator was on top of the hood brace on the driver's side. Here's are two pics of the '83. I actually think I have the actuator from that '83 in my garage.
