Background:
OK, so I went to Camping World (Tacoma, WA) today and they did an OK job of installing a Class III towing hitch for a tow bar on my 2016 Dodge Journey. However, they totally failed when it came to installing the electrical plug for the trailer lights. They were expecting a plug-n-play for the electrical connector they ordered. They ordered the wrong electrical part and so then they decided to hardwire my electrical lighting for the trailer into my taillights instead. They were almost done before I caught them at it, but they had the gall to tell me that they "did it that way all the time" even after I told them them the industry standard was to install a connector at the auxiliary trailer lighting bundle just in front of the rear bumper on the left side. They actually thought the wiring was supposed to be inside the cargo compartment space because they went to check there when I told them to do it that way instead. I had to tell them to look under the bumper. But it gets better the original service ticket used to special order the hitch parts contained the electrical connector part, but the final service ticket was minus the part but included something that was not there before, labor for "hard-wiring' was added. This meant they didn't intend to do it that way in the first place, but then couldn't figure out what to do so they did it wrong and wanted to pass it off anyway. Their manager was no better. He repeated the refrain of "we always hard-wire to tailights" even though the parts on the special order invoice clearly showed otherwise. Needless to say, they're going to get a credit card merchant dispute out of this. Camping World ... what bozos.
Of course, this leaves me with the original problem:
Where do I go to get the part that plugs into that auxiliary wiring plug to connect to a 4-wire flat connector for connecting up trailer lights? What is the part name/numberand who can I order it from? The terminating receptacle I have is a small white 5-pin female receptacle in a trapezoidal arrangement of a row of 3 pins and a row of 2 pins. The picture preceding journeyman's post, that is the only post that mentions this receptacle, is exactly what I have.
