I got the steps working.
BTW you Trail Lite owners should do some PM on the electrical connections. TL omitted a waterproof clamshell shown on the Kwikee parts diagram. It was supposed to go over the two wire connections I'm going to describe. There are two orange wires coming off the chassis which connect to black wires on the Kwikee. One for the step light and one for the control module. Their connectors are basic plastic covered spades and females of same. I had to pull them apart and put them back together to get power to the step and light. They were dirty but not corroded, but whatever, they were not working. I filled them with dielectric grease and called it good for now. Really there should not be ANY of the crimp type connectors used underneath a vehicle, exposed to the elements. I also re-did the ground wires because they were very shoddy and did not look healthy.
Anyhoo, once I got power, the step was still frozen. I took the whole motor and gearbox off (four bolts), and got the step freed up and lubed. Everything works great now. Well, except the step light. Which is funny because it worked when the step was frozen. I checked the bulb and it's fine. I'll let it go for now and see if there is a gremlin that goes away later.

This more or less completes the list of things (we know of) that didn't work at the purchase. I still haven't put water in it to check out the plumbing side of things, though. We are getting excited to take it somewhere soon.
