Mounting Orientation of Tuson Electronic Sway Control System

Question:

eTrailer, I see conflicting answers as to whether the tuson controller #335TSC-1000 should be mounted with label facing toward to the front or facing backward to rear of the trailer. The installation instructions don’t mention it at all, but all the diagrams in the instructions show wires exiting the controller to the drivers side. This infers that the label should be facing to the rear. An eTrailer answer to this question states the opposite: “The label side of the Tuson Electronic Sway Control System for Electric Trailer Brakes # 335TSC-1000 needs to face forward and be in a vertical orientation perfectly centered on the trailer 5-10 feet back from the center of the king pin like what you see in the picture I attached.” I would think this orientation is extremely important or how would the controller know what is left and right.

I reached out to my contact at Tuson and they informed me that there is not a particular direction the sticker on Tuson Electronic Sway Control System # 335TSC-1000 should face. So long as all the requirements are met, "up" on the label is facing up, the red dot is in the center line of the trailer and the red bar is parallel with the axle and 5 to 10 feet from the hitch ball it doesn't matter if it is facing forward or back. He also told me that a line has been added to the instructions clarifying this, because this has been a common question people have.

The benefit of having it face backwards is that there is less of a chance of road debris hitting it, since it will be mounted to a vertical surface and somewhat protected.

I linked a review video of the # 335TSC-1000 for you to check out.
