When I get home, I'm going to do some checking with my meter on the box functioning. I'm thinking there is something wrong in the small breakaway unit.
Your correct I got mixed up, the screw in conector is for a antenna. The small plug is for the brake away. The break away is just a switch, when the plug is in place the internal contact are held apart. Pull the plug the internal contact come together and close an electrical circuit. By pulling the small plug you should be able to use the RVI2 but without a break away function.
I just went to my car to verify. With the plug inplace on the break away box and my meter set to measure resistance at the small black plug that goes into the RVI2, I measured an open circuit. Removing the plug from the break away box resulted in an closed circuit.
By the way brake switches are like 10 bucks at autozone.
