The distance between most holes is 2-1/8 inches, with a 3 inch distance at the bottom; I have added a photo showing the distance between mounting points for a 5-bolt brake mounting flange; which is the exact same distance on the mounting holes of the Electric Trailer Brake Kit - Self-Adjusting - 12" - Left and Right Hand Assemblies - 5.2K to 7K # AKEBRK-7-SA.

So that's what your 5-bolt mounting flange should measure in order to mount the # AKEBRK-7-SA. To mount the brakes you also need the Mounting Bolts and Hardware for 12" Brake Assemblies # BRKH12.

I'd recommend using 10 gauge wire like part #10-2-1 (sold by the foot) for the brake power and ground wires as this will be more than adequate and will ensure you get plenty of amperage to activate the brakes.
