Most Popular Trailer Wiring for 2013 Freightliner M2

I mounted mine onto a piece of aluminum flat stock on the trailer “A” frame to reduce rock impact from Nevada’s gravel back roads. There really wasn’t good location on inside of trailer frame rails, was adding electric brakes and converting from 4 pin to seven. . I’m pretty darn happy with this junction box as it made rewiring rather straight forward. Our local 12 volt guru at the auto electric shop was duly impressed-wanted to know where I found it.

This box was used as part of an electric brake conversion on my trailer.

It has the required breakouts and grommets needed to make the wiring task the easiest part of the conversion.

Simple answer to how to keep your 7 way connector free of water and dirt. I affixed it vertically to the trailer tongue where it was convenient to access. The connector and cable now stays out of the way and covered against the elements when the trailer is disconnected.
