I did several coaches for customers who were retired and on fixed incomes.
That was what I said as the first solution and at radio shack about $8 bucks. The switches are located in different locations for operation of the steps from inside or outside the MH.
The wiring for multiple switch points and remote operation from the ignition and isolation is more easily accomplished with relays.
