[remcolent]

I have here a 4 wire impulse brake controler.

red wire (thin) to stoplight switch ?
Black wire ?
White wire ?
overhere black is normale used for ground but I don't know if that's the same in the US

Make and model of the controller is needed since the wiring in not the same from manufacturer to manufacturer.

Blue - power to trailer brakes
Red - enabling power from brakelights
Black - 12V power
White - ground/earth

For Tekonsha Prodigy P3 and other models.

Over here, black is ground in vehicles, and white is ground in trailers. Red is 12V+, except where white is ground, then black can be 12V+. So it's not uncommon to see a black coming from the battery, changing to a white where the ground is located.

It's all part of our happy-go-lucky nature.
