Newby question, electric brake problem

Hello
Just bought my first AS, it's a 1970 27' in great shape.
I have a Prodigy electric brake controller in my Tow vehicle.
I have used this unit on two previous trailers (non Air Stream) and it works fine, just plug and go.
I hooked my AS up for the trip home and immediately the back up lights came on, without the tow vehicle even starting, just plugging it in, they stayed on the trip home.
As soon as I got on the road I also noticed that the trailer brakes were not working. I stopped at the first rest stop and checked all of the wires in the mail plug from the AS, they were all connected properly to the corresponding color tabs.
I also noticed, that I can not back the trailer up (as the brakes lock up), unless I disconnect the plug, then it works fine, this must be a hill hold device with AS?
Sooo, the brakes seem to be working, but it must be wired improperly from the AS. Any suggestions???

After thought, the brake lights and signals and running lights all work fine......

Does the trailer plug have round or flat pins?

The plug configurations have changed over the years. In the 70s the center pin was the charge line from the TV. Now the center pin is the backup lights. Because of this your charge line is powering the backup lights all the time. Your backup light line is powering the brake magnets, that is why you can not back up the trailer. The following diagrams should help getting the wires straightened out.

Inland Rv, the plug is round (brand new) with a round center pin and several flat pins in a circle around the outer edge.

Fly caster, bingo, that sounds like it, thanks for the schematics....

That connector is famous for problems due to lack of use.

The original connect on your Airstream used 7 round pins, that some call aircraft terminals.

You can soak it in the mud, plug it in, and it works, the first time.
The flat pin type, is usually a headache everytime you hook up, due to some of the pins not making contact, until you clean it again, and again.
