Caps: Welcome to the forum. Been reading your post for sometime now trying to figure how to help. Keep in mind that this a typical installation.

The contoller needs a 12v batt signal to the black wire through a 20-30a fuse or c/b.

The red wire is connected to cold side of the stop light switch. In other words that wire should read 12v when the brake pedal is pushed.

The white wire is connected to a good ground.

The blue wire is routed back to the trailer plug.

Most controllers will have a sensor light that comes on when the trailer is properly hooked up electrically for the brakes.

Another thing is to have a good ground on both the trailer and the truck going thru the plug. Don't rely on the hitch point for a ground.

Hope this helps some............Steve
