Brake Controller

Hi I have a 2002 HR Scepter and am hooking up a Brake controller and am Looking for a diagram. This is a diesel and it has an exhaust brake and I don't want the brakes coming on the trailer when I use the exhaust Brake. I am installing a Prodigy 2 controller. I would appreciate any help I can Get. I know that this unit is not prewired for a brake controller.

You're looking at a fair amount of work to wire in the Prodigy. The DP's don't have a brake switch like a gasser, which makes it difficult to do. Lately, many have been buying the wireless units and skipping the hassle.

If you don't want to go wireless, here are some suggestions: Go to your "run bay" (large bay under driver's window and start there. Pick up a power lead out of the big black box, (plenty to choose from). Connect up a wire for 12 volts and add a fuse. Pick a suitable ground connection and wire in a ground. Next, (from that bay) run a wire the length of the coach to the rear trailer plug. Lastly, there is a wire in the loom at the bottom of the box that says brake lights. I tapped into this on a neighbor's coach and found it did not provide a full 12 volts, but was active when the brake pedal was depressed. I tapped into this line and then connected it to an automotive relay. I added 12 volts to the relay (again fused) that would give a full 12 volts when the relay was activated by the brake light wiring.

Once you have this all done, you can feed the four wires up through the top of the run bay and into the armrest/control panel inside the coach. Once in there, you can fish it out the front of that box and under the dash.

It is more than likely already pre-wired if you have a 7 way on the back of the coach. The wire harness for a brake controller will be under the dash and bundled together with wires identified by a legend on a tape around the bundle. It should only take 30 minutes to an hour if you are new at installing the brake controller.
