Tekonsha Powered Tail Light Converter w/ 4-Way Flat Trailer Connector and Install Kit
The wiring harness and trailer hitch from ETrailer work great. No issues whatsoever. It works as it should. FTIW, I have self-installed hitches in the past on other cars and consider myself a savvy shade-tree mechanic. Although the installation of both products didn't look that difficult, and there are a wealth of vids by etrailer, my problem was the jacking and safe under-body access on the Tesla. I just don't have the facilities, and was wary by the weight of the car plus warranty issues. So I opted for a pro intsall job. Given the nature of the beast, and this is no reflection on etrailer, if I were doing it again I'd prob just spring for the pricey Tesla install. Since I live in the sticks, I had to drive pretty far anyhow to find an installer, let alone a good one. The bumper removal etc. for the hitch install isn't difficult, just that pesky wiring and a safe work condition.
Install on 2018 Mercedes Benz CLA250 w/LED tail lights: There were no guides I could find so I'm posting this for other etrailer customers. These are my installation notes and the kit operates correctly. There are other ways to do this, I'm sure. It isn't necessary to remove the tail lights, there is a removable piece in the trunk carpet. I removed that and the plastic trim panel in the middle. The tail lights have 10-pin connectors. On the left there are 8 wires on the right there are 7. My thought is maybe this has something to do with the european style parking lights. After probing I found this: Left Side: Turn/Brake - Yellow with White stripe Running/headlights - Black with Orange stripe There is constant power to the Green with White stripe Right Side: Turn/Brake - Light Blue with Red There is constant power to the Green with White stripe I had to splice additional wire to mount the module where I wanted it. The final connections were: Module Brown to Left Black/Orange Module Yellow to Left Yellow/White Module Green to Right Light Blue/Red Module White to Ground Module Black to Battery Module Red Terminated (unused) The positive electrical connection I made was under the hood, off the fuse box. Terminated to one of the lugs, covered with wire loom, and run into one of the cars wire bunches. The 4-wire hitch output is terminated with a CURT tester (If you put one there, you'll always know where it is when you need to troubleshoot something) This vehicle is completely covered on the bottom and running the wire can be very time consuming if you want it to look tidy.

20 Ft 4-Way Trailer Wiring Harness - Wishbone Style - 30" Ground
Wiring worked perfect for my project. I replaced the wiring on my 14 foot utility trailer. If I was to do it again I would buy the next length up. I would have liked to have a little extra wiring if I was to ever need it.
Worked perfectly with the trailer lights.

Adapter 4 Pole to 7 Pole Vehicle End Trailer Connector
i had to replace these two items as my dear daughter went down our goat path driveway too fast. they replaced the originals from etrailer from the prior year. shipping is timely and customer service actually helps! i wired from battery to controller to hitch myself, and everything fit.
This product works as expected. There is not too much to the installation, just plug it in properly and mount the ground wire. I did not find an easy way to mount this to my wife's Odyssey, or to the trailer hitch (item# 75270). Luckily, I do prototype design and manufacturing. So I came up with my own solution. I designed and made my own bracket to mount the 7 pole to the trailer hitch. It works like a charm, and looks great!

7-Way Molded Connector w/ 10' Cable - Trailer End
I upgraded my trailer from hydraulic to electric brakes and rewired everything to neaten and freshen up things. Its a nice piece. I recommend.
The overall quality of the cable is impressive

Hopkins 6-Way Connector with Jacketed Cable - Trailer End - 8' Long
The plug was missing the set screw and collar that compresses on the cable to prevent strain on the connectors when removing the plug. You can see the set screw clearly in the product picture.
I like this style of plug because it is molded and is important in keeping water out of the plug. It is conveint because it has the right colored wires. I have a water tight termination box with studs that it is wired into. Once I damaged the cable so I opened up the terminal box installed eyelet lugs on the spare pigtail, and installed it in a fiew minuets. I keep a spare on hand with lugs on it so if I have an accident I can quickly replace it. I also use these on some of my smaller tow behind equipment. that's why I like this size plug it isn't real bulky.

Hopkins Endurance Flex Trailer Connector Adapter w/ LED Circuit Tester - 6-Pole to 4-Pole
I was very glad to find this adapter so I can hook my bumper pull trailer to the wiring that is already in place for the gooseneck. Easy to order, delivered fast. Problem solved. Thanks
Choosing the correct connector for my pop-up camper and F 150 baffled me before I asked etrailer for help. I got that help, bought the etrailer connector, and it worked like a charm. The lube that came with the connector was an unexpected bonus. Many thanks.

Hopkins 7-Way RV Style Connector with Molded Cable - Trailer End - 8' Long - RV Standard
7 pin connector separated from cable. I was expecting that "Molded Cable" meant that the connector was fused to the cable insulation but instead, the two separated almost immediately after I installed it. It still works fine as the wires are connected securely inside the connector but with the outer covering pulled out like this, I don't think it will last very long.
Çable good but after putting new 7way plug on truck cable wire colors did not match etrailers picture

Bargman 7-Way, RV-Style Connector w/ 12' Long Coiled Cable - Trailer End
Excellent addition. I was having an issue with chaffing the straight oem wiring when towing my gooseneck with my F-550. This coiled wire completely eliminated that problem.
This coiled wire connector is a must for travel trailers as the straight one that came with the trailer drug on the road until it wore through on a busy interstate highway and subsequently locked up the brakes at approximately 60 mph. The way it stopped the truck and trailer I thought the transmission exploded. It would not move until I disconnected the trailer batteries. Make sure you order it long enough as I did not twice! E-Trailer was the best at changing my order before shipping and again when I returned one that I still thought was too short. I still can't say enough good things about how they have treated me through multiple times I have ordered things from them,definitely my go to for anything I need for our trailer.....

Adapter 4-Pole to 7-Pole and 4-Pole
Really nice trailer wiring adapter. Very easy install. Takes about 30 minutes with all the tools needed. Drill, 7/64 bit for pilot holes to mount the bracket, flat blade screwdriver and 11/32 nut driver and two #10 self tapping metal screws with locking split washers and a couple zip ties to tidy up the wiring harness.
This is a great adapter to retro fit connections on my 2011 Expedition. Simple to instal and great support from etrailer.com.

48" Long 4-Pole Loop with Cover
The items I ordered will allow me to adapt my utility trailer for transporting my sea kayaks. Curt and Hopkins are both quality manufacturers. On a shipping note, the box arrived at the Post Office broken wide open. Your shipping folks need to wrap small, heavy, items in bubble wrap. Then stabilize it with foam peanuts. Just putting it in a box then stuffing the box with craft paper does not cut it. Items were not damaged so I am good to go.
I have now installed the following on my 2017 Wrangler: Brake light relay kit . Hopkins Towed vehicle Tail Light wiring kit. Blue Ox base plate. Blue Ox Patriot Portable RF Braking System. All of this has taken about 3 days of work spread out over a week or so. Overall it went well. Not too many surprises. Crawling around under a car at 71 is a bit of a strain but I'll get over it. I must say that Donna P. has been a wonderful source of great information and has stayed right on top of the process. eTrailer has been a great source for this project. I would recommend you all with no hesitation.

Hopkins Endurance Quick-Install Trailer Connector Adapter - 4-Way Flat to 7-Blade
It took awhile to receive my order, but I was informed by e-mail and was kept informed when I should expect delivery. Luckily, was in no rush, so I would reply and wait for an update from you. i received the connector in good condition. Thank you!
Installation went well and works fine. Only issue was the screws included with the product were not the right ones so had to replace which wasn't a big deal.

Adapter 4 Pole to 7 Pole and 4 Pole w/Test Lamps
Not too difficult to install, but I would recommend using a car lift so you don't have to work from your back (review includes wiring harness and Brake Controller)
Very easy install. My truck had a precut hole in the bumper for the plug. I then hooked the spare 4 pole plug into a Reese Universal mounting bracket and mounted it onto the hitch.

Hopkins Endurance 4-Way Flat Trailer Connector - Trailer End - Ergonomic Design
I rewired my light bar for my boat trailer with the items I purchased. Before I built the the light bar, every time I used my boat trailer I would waste valuable sailing or fishing time repairing faulty lights. The do not last long when you submerge them in salt water. This light bar now version 3.0 have given little trouble over the years
Great product. Works well when I had a broken connection on my 4 way plug end on my light-up hitch cover I bought from y'all a while back. Always a happy customer. Thanks, George.

7-Way Molded Trailer Wire Connector, 6' Long
Only gave 4 stars because it was a bit confusing. I have a lot of auto wiring experience; from car stereos,amplifiers and all manner of accessories. All of the info on etrailer indicated that the color coding didn't match up. So I went into it disregarding the standard color coding, when in fact it was just as it should be.
Good thick rubber and plug works perfectly.

Mighty Cord Trailer Connector Adapter - 4-Way Flat to 7-Way RV Style - 12" Long
This is my second order with etrailer. Both experiences with your company have been very positive. The knowledge and friendliness -along with following up on orders and satisfaction have been much appreciated. Brittany, the customer representative, is a huge asset to etrailer.
Exactly as described and what I needed. Delivered quickly.

Hopkins Tail Light Converter with 4-Way Flat Trailer Connector
I used the Hopkins 3 to 2 converter to make a 6-pin round to 4-flat connector for my Winnebago View motorhome. While there are 6-4 plugs available to do this, they do not work on the Winnebago View (no brake lights). This adaptor works great.
This device was no help in connecting my five wire trailer to my four wire goldwing. I ended up having to use a number of diodes in the trailer wiring to make everything work properly. My trailer had red LEDs that were used for Brake, Turn & stop and I had to get the brake and turn function to share the same lead on the light fixture.

35 Ft 4-Way Trailer Wiring Harness - Wishbone Style - 42" Ground
Works very well after re-wiring trailer lights with waterproof distribution box.
2 things. 1st@: I think there should be an option to pick tinned wire. 2nd: The ring terminal for the ground needs to be bigger.

Wesbar 4-Pole Flat Connector w/ Jacketed Cable - Trailer End - 4' Long
I have been very pleased with etrailer orders recently. Everything shows up when expected and products are as expected. Attached are a couple before and after pictures of my recent project to add lights to a cargo rack per my wife's request. Thanks for the professionalism of all at trailer
Heavy duty plug that has a good snug fit and I like the jacketed cord that provides strength and extra protection.

Hopkins Endurance 5-Way Flat Trailer Wiring Kit - Vehicle and Trailer Ends - Ergonomic Design
etrailer is the only place I could find this item. It is much higher quality than other flat connectors, with weather covers and big finger/thumb grips to actually hold onto the connectors and easily separate them. I used the 'trailer' end in my adapter unit.
The female connector is attached to the swing arm of a motorcycle to provide lighting lighting for a trailer pulled by the motorcycle. This means that there is likely much more movement in the harness than for an automotive application. I've never had a problem with any part of the harness. I found this product to be exactly what I wanted, well made and easy to install. The protective cap functions well as it remains pliable (flexible) after a year of use, and while it has never fallen off in use, it is easy enough to remove before making the connection. It has done the perfect job of keeping mud and other detritus out of the contacts. The recessed nut holders also function well and is one of the reasons I chose this wiring kit. This wiring kit gets high regard and recommendation from me. All of my purchases from etrailer have been solid products delivered at reasonable cost.

Wesbar 4-Way Flat Trailer Wiring Harness - 20' Long
I'm extremely satisfied with the wesbar 4way flat trailer wiring harness I purchased from etrailers.com. It was very easy to install with no problems. As long as you connect the wires correctly (example) white wire to white wire brown wire to brown wire you won't have any problems. If I ever need another one I'll know who to order it from etrailer.com.
Just what I needed for a boat trailer rewire. It would be nice if two more brown wires were added to take care of the yellow tongue lights/running lights that are partway along the trailer. I will splice in.
