Howdy all. I'm picking up a single axel enclosed motorcycle trailer next month. It has a 4 prong plug for the lights / wiring. I was planning to pick up an adspter for the 7 pin on my 2014 1500 but I heard these trucks may have a factory 4 prong tucked up in the wiring? Anyone know if this is valid? I'd chk it myself but I don't have access to my truck right now / away at work. As mentioned 2014 1500 crew cab 4x SXT with tow pkg. Thanks.
