Question:
Got a 2015 dodge ram truck. I need a custom wiring kit to replace my existing towing wiring. Would like to have one that plugs in at the tail lights and run to the back replacing my existing 4 / 7 blade plug

Hello Geroge, thanks for reaching out. All of the custom fit wiring option for the 2015 Ram are designed as replacement for the factory 7-way. If you want something that connects in behind the tail lights and bypasses the factory wiring the only option would be to use a universal splice-in harness like the Curt # C59236. Then you can use the Universal Installation Kit # ETBC7 which will contain all of the components needed to wire your truck with a brand new 4-flat and 7-way.
The # ETBC7 kit also contains all of the necessary wires for a brake controller, like the Tekonsha P3 # 90195 which is what I recommend.
