The trailer junction box I ordered had to be mounted further back than planned and the original cable was too short. This one was purchased to replace that and is noticeably higher quality all around and has the dual metal fins inside to accept/hold the pins. The wire itself is also more playable than the original. Better quality all around.

I used this to replace a harness from a horse trailer that wasn't making good connections at my truck. The old harness had corroded single prong connectors which I assume was part of the problem. This Curt harness is making a great connection every time I use it. Yes, it is an RV color scheme, so the colors won't match exactly if you are replacing a standard trailer harness. RV harnesses seem to be easier to find than standard harnesses, so I did a little homework to make it work on a trailer with a standard wiring color scheme.

My original wire harness was 8-feet long. Had issues with it not aways staying in place on the truck receptacle. I tried to put a new end on the original, but there was not enough slack in the cord to allow for turns. So, I had to invest in this item. I had a short in one of my lights that I did not know about originally, so that threw me off in addition to the wiring comments on this item. Some are recommending swapping colored wires. For my Ford pickup and 2001 Fleetwood Chateau travel trailer, it ended up that the colored wires from this wiring harness to the camper match exactly. The yellow wire (accessory) is not used, so I taped that one off. I encased the wire in a larger split loom (see pic) for protection from the truck to the RV Junction Box. Original wiring was routed the same way with no protection. I wrote the connections info underneath the camper next to junction box for future reference (see photo for myself or future owner). The wiring harness worked well for my application. If it was not for the short (mice damage) it would have been a breeze to install.

As there are different wiring systems for different applications, I recommend you double check your color-coded wires match the replacement harness. (RV wiring systems may vary from a utility trailer)

Beware that it is RV wire colours which is different than SAE. My lights didn't work right the first time as I just matched up the wire colours, but the RV standard switches them around. Worked fine after I rewired. Very heavy gauge and thick outer casing so I expect it will last.

Good, heavy-duty plug, wires (#10/2 conductors, 12/1, 14/4) and sheath but the same wire colors didn't match up; however; I was able to make it work. Other reviewers noted this might be the case/problem. [UPDATE: I've been using this plug for several days and really enjoy everything working properly and reliably. No more...will it work? Maybe? My electric tongue jack seems even more powerful than before with positive, clean, solid connections. Bottom line is I wish I didn't wait so long to fix this.]
My Mopar truck receptacle (below tailgate where you plug in the harness plug) received a Phillips 7-way trailer/RV harness (10/2, 12/1, 4/14 wires). The Phillips harness uses (what I believe are) inferior single blade connectors. The plug was worn out and became unreliable, so I decided to replace it. This new Curt plug is actually a double-blade resembling a typical electrical wall outlet (i.e., the Curt female connectors inside the plug contact both sides of the male blade inside the truck receptacle vs. just one side on my old Phillips plug. The old Phillips was metal on one side and used the plug's plastic on the other side to "squeeze" the...
