Heavy Duty 7 Way Round RV-Style Trailer Connector - Replacement 7 Pin Trailer Wiring Adapter Plug

This is a nice solid plug. All other plugs I have found are thin plastic. This is a solid metal and thick plastic plug. The metal in the middle where the wires exit is a bit to work around but all and all it is worth the trouble.

The connector was simple to connect wires to with screw terminals. The wire collar seems very solid.

I used this with a few other parts from Amazon to make a switch for our RV lights to come on/off automatically with sunset/rise. The multiple pieces made it much easier to put the parts in. The one pre-built I found was around $80, this allowed me to build one for around $20. It's not as pretty but I'll take the savings and I'm able to adjust the light sensitivity.

The screw on nut and gromet to connect the cable to the plug works well to hold and be more water resistant that the typical plug. The connections for the wires were a little more difficult to get a wire under than others I have used. They seem a little flimsy. The white ground wire would not go under the original clamp and I reused the one from the plug I replaced on it and a couple more. Overall, it is better than most I have used in the past.

A little confusing on the wiring directions but finally got it.

Very nice quality plug and reasonable priced. All connections/schematic clearly marked on the plug & the box. The threaded nut along with the water seal makes adding protective tubing to the wire harness easy and stronger than the typical "pinch" style end.

Was easy to get hooked up. I was replacing and older plug so I had a pattern of sorts to follow.Plugged in super solid and no further "trailer Unplugged" warnings on the dash.Time will tell on how long this works.

Most vehicle side plugs are not water/ weatherproof. I wanted that to prevent corrosion of the wires. This one is just that. 100% seals around the wire and construction of the product is great. I would recommend this to anyone
