[Glenn and Laureen]

The backup lights on our 1984 Newell Classic do not work. They are located in the rear bumper. After extensive (for us) sluthing, Laureen and I have concluded that there is some sort of switch or relay located under the gear shift that is not sending the proper signal when we put the gear shift into reverse. I have attached a couple of  pictures (below) of the suspected small cannister device. What is this thing called and where do I buy one? How do I get the old one out?

We came to the conclusion that this small switch is the culprit after doing the following:

1. Removed the lights from the bumper and hooked them up to a 12v source. They worked fine. We reinstalled them after cleaning up the housings and adding ground wires (they were originally self grounding but the housings are 36 years old).

2. We confirmed that we have continuity from that switch over to the front fuse/terminal panel in front of the passenger seat, then back to the panel on the outside rear of the coach and then down to the backup lights reinstalled in the rear bumper.

3. We have 12v on one of the wires on that switch but not the other one (tested with the coach in reverse and the ignition switch in the on position. 

We think that little switch is not closing the circuit to allow current to flow when we turn on the key and put the gear selector into reverse. If that is true, how do I get it out? Where do I find a replacement? What is this thing called?

Thanks for any help.
