Easy to install. Works great. Only complaint is the Snap/Ties are not located in the exact spot. It should have been left loose or unattached so I could have used them in the correct spot. I had to replace them to get the wiring harness attached to the frame and body.

Harness is made very nice, not made with cheap components. Shipping was timely and easy to order. Great direction for installation 15/20 minutes

This was literally “plug and play”! Instructions were straight forward and the installation took less than 30 minutes!

Very nice harness and easy to install on the LR3. I have the proximity sensors disabled so didn't need to go to a dealer to reconfigure the body control module for a trailer.

This kit fits exactly with all hardware and instructions, took me 30mins. start to finish in my driveway. The sales / shipping team kept me informed as to when the order was processed- packed- shipped. Excellent professional people to deal with. I will purchase from them without hesitation in the future.

Faster than expected shipping and installation took about 10 minutes. The video they have up for installation was helpful as well.

The product is as simple to install as explained in the video, there really is nothing that comes up as a surprise during installation. It took me about 1.5 hours to do it (and I'm no mechanic). It's simple, comes with the screws to secure it in place as well as foam strips, little pin things and zip ties to get everything more or less professionally installed. This product cost me (with shipping to Canada) $255. The best quote from a mechanic was $750 to install a wiring harness. This was a no brainer for myself and glad I did.

Beautifully made, exact length, high quality, 20 minutes to install. Hardest part was getting the plug block into the rear bumper. (Yes, it does really fit. Try sending it in upside down.)

Came fast, takes flat and round plug and mounts behind trim plate. Priced well below what local hitch franchise wanted to charge.

Perfect fit, works exactly as expected. When installed it looks factory.

Product appeared to be OEM. I was surprised at how well made all the fittings and grommets were. I will feel confident in buying more products from this fine company! Thank you! P Lewis

Rating it from 1 - 10 it's defiantly a 10. I liked it very much and I will recommend it to all my friends and family.

This is a "plug and play" solution and was an easy install. It takes a little wiggling to get the trailer end in place, but fits perfectly.

Did not know product does not work as designed because early lr3 it's set up for Led trailers so you will get trailer lights flickering all else works well I'm going to try the LED resistor on my trailer lights

Took no time at all to install and easy instructions with pics. 40 mins and I was ready to plug in. Thanks guys!

Everything worked great, but the screws were too long. The whole reason I went with this product rather than cobbling together a less expensive alternative was too have everything fit correctly and save me time in the installation process.

By: Richard Bucher

The kit worked as described. The online video tutorial showed everything I needed to do the install myself. I had no problems and I am not a mechanic.

By: Morris Yarnell

The issue I had lies with Land Rover and the tight space allotted to install the wiring harness, not with the product itself. I received a call from Atlantic British staff to help complete the installation and it was very timely and truly helpful. The harness was well made and seems to fit well.

Only issue was plug was to long and had to be filed down to fit in the bumper. Other than that really nice product. Would absolutely recommend this product.

By: Bryan Marcum

Simply plug and play. Two people makes it a little easier. If the wire section coming from the tail light/cargo area (product comes in two pieces) was one inch longer, it would be easier for one person to complete. All in all, great product.

The harness was pretty easy to install, best if you do the bumper half first then you can hook up the connections and pull the top portion up through the bumper. This install took 25 minutes for me.

Install was super easy and like everyone else mentioned, the quality of this is absolutely top-notch at an unbeatable price. The videos that AB put together via Doug, are unmatched. You guys are awesome!

Quality of the product was as good as OEM, for substantially less money. Printed instructions were included and made the installation easy. Plus they have a YouTube video if you need a little help installing it. If you need a trailer harness I can definitely recommend this one and Atlantic British. This was my second order from them and they ship quickly and securely. Thanks for a first rate product at a first rate price

Love the Trailer Harness- Easy Install- just did not receive TY-Raps or Mounting Bolts-(as per the enclosed inventory sheet) Had to purchase local

This was a very good buy for a land rover part. The quality was excellent and instructions were easy to follow.

Easy to install. Instructions accurate and complete. The web site provides good instructions as well. Tip could be added to the instructions to run a tap through the exterior holes to ensure bolts install without stripping.

I have to commend Atlantic British for developing this alternative harness to the expensive factory original. For a fraction of the price you get a product that matches the original in quality and design. Installation was a simple 20-minute process using the AB videos as a guide. A simple, affordable solution.

Took about an hour to install, but it works great, online video and written instructions were very helpful.

I rarely ever write online reviews but this definitely deserves a thumbs up. I have done a fair amount of work on my LR3 and have never had a project go so smoothly. Much of this was due to the step by step instructions WITH pictures that made perfect sense. There was never a point where I was at all stumped about what was supposed to go where, or what was next. Excellent job, thank you!

5 out of 5 stars | Date Posted: 04-29-2014

By: Robert Courcelles

The instructing were very easy to follow. I just had to open the cover on the plug to wiggle it in the bumper! The rest went in smooth! I would recommend this product if you want an easy install and want to save time instead of splicing in a harness that will be prone to corrosion failure.
