Yes that is correct, the bow will always face forward on electric drum brakes. The magnet will be on the bottom and the arm that the magnet is attached to will bow towards the front. Also the shorter brake pad will always be in the front of the assembly and the longer brake pad on the rear of the assembly, the reason is that the shorter pad will contact the drum first to slow the trailer down and the larger pad will then contact the drum to finish stopping the trailer, so both pads will wear evenly.

Also the magnet does not have to be wired in any particular polarity, one wire is for the power and the other is a ground.

I am sending a few links to Dexter 10 inch Electric Brake Assembly - Left Hand, # 23-26, and Dexter 10 inch Electric Brake Assembly - Right Hand, # 23-27, to show you how the right and left side assemblies will look.
