Easier Way to Wire in a 7-Way to a Trailer that Has 6-Way

Question:

I am trying to rewire a trailer 16 that I need a 7 flat and a 4 wire flat I was wondering if you have a pig type wiring harness so I can hook up either or the trailer has a 6 pin type connection on it now but Id like to rewire all new wiring and the trailer has brakes so Im trying to figure it all out so I can completely rewire while I have all the floor boards up my Ford truck is already wired with both the seven and for pin connector so Im just doing the trailer now.

The easiest way to upgrade a trailer to a 7-way or wire in a new 7-way would be with the 7-Way upgrade kit part # HS381-9000. The junction box mounts on the trailer and then all of the wiring then runs to the box and you're set. You wouldn't want or need to also run a 4-way harness to it as well. If a trailer needs the 7 circuits to function there wouldn't be a way to tow it with just a 4-way.
