So your RV is bit older then what I'm used to working on, but I can give my thoughts.
Horn. You say you have power to the tabs. Have you tried to ground them manually? some horns are ground interupted and some can be positive interrupted. by touching the tabs together you should have a horn go off.
If this doesn't work. its one of 2 things. the ground wire is broke somewhere in the harness. and or you have a horn relay that is not operational.
A relay on your unit would be under the dash and or in a power distribution box inside the engine compartment. See if you can obtain a FSM online or Factory service manual. it will tell you everything you ever wanted to know about the drivetrain.
Very uncommon would be a horn that stopped working you can use leads to power off battery and touch to ground that would let you know the actual horn works and you can work back from there.
On your Cruise. What isn't working?
Typically older cars some have clock springs some do not. if you have buttons on the steering wheel area you might have one. if its a tree stem or the unit that comes from the side that works other functions. those modules are very common for failure. I would start there for electric operation. they fail quite often.
the other thing is the the type of Cruise you have most older vehicles have vacuum assisted cables that operate the TB or carb. check for vacuum.
also cruise usually only works on speeds over 30mph so it can be hard to check in the driveway.
You problably don't have airbags but if you are ever working around bags you need to know how to disarm them properly or serious injury and damage will occur.
hope this helps a bit.
