Correct part for the job. No jumpers or splicing. Hardest part of the job was getting sticky back door open.

This converter worked perfect to switch a European connector to American. It took no time at all to install, and the wires are long enough to drop it down through the tail light. Highly reccomend.

This is a great product and such a lovely ordering department. I called to make sure I was ordering the right part. I installed it yesterday and it was very easy with nice colorful pictures with each step in the directions. The only slow part of installation was the tiny zip ties(they could be bigger) as I had to lie under the bumper to zip them to the wiring. The wiring kit was completely designed for my Rover. This part was 1/3 the cost of the price at the dealership. Thanks again. Beth

The wiring harness for the trailer lights was the exact fit and super easy to install. Directions were adequate, and the product is exactly as advertised and seems to be built of perfectly fine quality.

Simple plug and go. The only thing I did different was I used wider wire ties. This system is so good that when you first turn on the key the computer turns on the trailer icon.

With the short video. it took longer to take out the 4 screws on my taillight ...than to install the wiring harness. Eric really blew it up with the super awesome shipping. Thanks to all!!! A++

The ease of installation of this wiring harness makes the extra cost well worth it, take out 4 screws from the tail light, run the wires through the bottom, connect it to the plug, use the sticky back to secure the adapter, put the tail light back on and you are done. Excellent part, now I can pull my little boat everywhere behind my Disco 2. Thanks folks!

I give high ratings to products that do exactly as advertised, work the first time and are a good price for the function they have to perform. This fit all those requirements.

Great Wire Kit! Medium gauge wires came packed accordion style and not easy to straighten in cold weather (instead of rolled in a circle that makes for straighter line out of the packaging). To help the cord down through the long opening down to the bumper I had to use a straightened metal coat hangar to help feed. Other than that the install was super easy, simply plug and play. Installed in about 15 minutes and works like a charm.

This kit was used to replace the kit uHaul installed. Easy and precise instructions and it's super easy and works perfectly. This is THE solution for trailer wiring on your Rover. Good product build, good directions and works! I would recommend this for anyone and any skill level. AA++

Easy install took probably 20 minutes. I turn a slow screw driver.

This is perfect for a small trailer using the standard 4 prong. It would be nice to see the full set-up for additional trailer wiring though.

I like this kit because the instruction was easy to follow. I can now tow with my LR.

My 2004 DII had an aftermarket install that the shop went the extra mile of soldering the wires into the harness. A pain since the harness does not come out of the lamp hole so you have to work down in the hole. I cut the added wiring and used liquid electrical tape to seal up the damage. Once this unit arrived it only took a few minutes to install. I put dielectric grease on the connector hooked it up and everything worked. My only complaint is that mine did not come with double sided tape on the module but I had some so it was not a deal breaker. Makes the connection quick and easy, why make your life more difficult to save a few bucks and then have to undo it later.

Product came as listed. Easy to install. Appears to work great.

It was snowing, it was windy and it was cold. Not the time you want to really work on a car, nevertheless fidgit with zip-ties. But as the instructions states you only needed to take the right rear light out and feed the wire through. Super quick and have since dragged that connection through all sorts of mud, water and salty snow. No problems, no worries.

It was as advertised. Only tool needed was to remove right rear taillight assembly

I almost wired up my own to save a few bucks but was super glad I did this. Installs in 5 minutes and works perfectly every time.
