'73 Int'l Sovereign Brake wiring

Does anyone have a diagram of the brake wiring from the front where the cable attaches. Lost my brakes and and tracing thus far has not improved the situation. Does the 1 brake wire going to the trailer split to go to the left & right brakes??? Or does the one wire split closer to the front axle and go to the left and right brakes ??? Any color code info?. All 4 pairs of wires coming out of the belly pan near each of the 4 brakes are black and white and are enclosed in a gray outer cover.....H E L P Please.....In advance I thank you.....JC

How it's exactly wired depends on who did it.

The only way that it must be wired is that the black and white wires "MUST" connect to each backing plate.

That's a "parallel" connection.

The white wire is grounded, typically under the front underbelly, and the black wire goes to the 7 wire connector.

The way mine was wired, and I have no reason to believe it wasn't the factory original wiring, was like this:

That gray jacketed wire begins at the front of the camper at the 7-way plug, where the umbilical plugs into the front of the camper from the tow vehicle. From there, it runs along the road side main frame rail in the belly pan back to the center of the belly pan between the two axles. From there, there are four pieces of of that same gray jacked cable that go to each brake/wheel which is attached to the main wire from the 7-way (in the case of our camper with a wire nut). Does that make sense?

Brake wiring

I am assuming the grey jacketed cable has two conductors (wires) inside of it. Lets say they are "1 black" and "1 white". If the wires comming out of the back plate of each wheel are black and white. It doesn't matter where the main cable splits other than to conserve on wire. Just match the colors and connect the wires. If they are say red and white at the back plate, hook the red to the black and the white to to the white. At the hitch, connect the white wire to the frame of the trailer there should also be a wire comming from the 7 pin connector that is attached to the frame of the trailer commonly refered to as "ground", although it is a misnomer. Connect the black wire to the 7 pin connector. If you have a break away switch, then there will be additional connections. We can deal with that later.

No brakes

I forgot to mention. Are you sure you have power to the 7 pin connector when you apply the brake at the TV. This voltage will vary depending on where you have your brake controller setting adjusted. For now set the brake controller to its maximum setting. If you know how to use a voltage tester or a Volt/Ohm meter (VOM). Jam the brake peddle down or have some one hold it down and check for voltage at the connector on the TV first. If there is no voltage, then the problem is not with the trailer, it's with the TV. Keep us posted as to the progress.
