My truck listed above has intermediate power controlling the wipers heater fan and transmission indicator. It acts like a lose wire. Comes on, goes off, over the entire trip. Can anyone describe a wire that would feed all these instruments?

It sounds like the ignition switch is going out but to be sure we can use a test light to confirm the issue. When these accessories are not working you need to test the output wires from the switch. here is a guide and the ignition switch wiring diagrams so you can see which wires to test:
