Best 2009 Volkswagen Jetta SportWagen Trailer Wirings

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.

Excellent. The only down side for my Lexus RX300 was not having an “easy” way to mount male 4-way next to hitch rather than stowing it beside tire bay. No big deal just a plus.

I have ordered from Etrailer several times over the years. Always have exactly what I need. Good prices and fast shipping. Could not be happier. This wiring harness was perfect. Installed it in a few minutes. Thanks.

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!

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.

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

I installed this connector on my travel trailer. The original connector had become loose and would fall out if not retained by the tab on the bottom of the connector. After a year of usage The Pollack connector still snaps into place and fits tight. Good product.

Routine trailer maintenance. Absolutely nothing worse than fighting trailer lighting or electric brake issues when traveling.

This was easy to install looks great and works excellent. have had on issues with this product my trailer lights are always working and keeping me safe.

Installed a Blue Ox Base Plate kit on a 2015 Cadillac SRX. The base plate arrived promptly and was well packaged considering its weight. Watched the videos etrailer provides and used them as a step by step video guide. The videos were a big help. Installation is not too difficult if you're mechanically inclined. Had someone help with the installation but one person can perform the installation. I think the base plate is well engineered and everything fit as it should. Love the fact the installation is so well hidden. We have about 400 miles on the installation and have had no issues. Thanks to etrailer for a great price, great service, and great product support.

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.

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.

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.

Everything worked out well. On time and fits perfect. Attach hitch setup and my new Ridgeline. It comes with a 2" inch receiver and I have a full compliment of 1.25. stuff from my previous car. All from etrailer i must admit! so I needed the 2-1.25 reducer, a good lock, and the 7-4 reducer for my goodies! Thanks for the grest service

I used this outlet plug to have 12 volt to power our shuttle pump on the water wagon to pump chemicals into our chem farm mix tank works really well easy to wire and very nice looking very durable .

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.

Overall, I was very impressed by this connector. I used it as an in-bed connector for my gooseneck trailers. The plug seems to be a quality product, engineered to stand up to some abuse. I like how the mounting bolt heads recess into the connector and also how the bottom of the connector is elongated to help support the weight of the plug and wiring. I think it has a great shot at lasting for a very long time. The hinge is predominately plastic that will not corrode and break like the many I've had in the past.

Great Product quick and easy install.

Worked out awesome. I bought this for a buddy for his used truck. The previous owners for what ever reason took it. Plugged it in and worked flawlessly.

It is a direct OEM replacement, easy installation. What I liked most was a real person answered my call and took my order, Katherine was very polite and knowledgeable. Thanks again. CJ

Still works great. The light up feature is great for knowing if a lighting problem is the vehicle or trailer.

The adapter works great. Actually, this was the exact replacement my trailer originally had. I tried one other adapter, not same brand and it didn't connect securely, not allowing a good connection.

I never used it. It does not fit my motorhome. Still sitting in my garage.

Exactly what I was looking for. Easily connected to my existing 4-way without any additional wiring. The 7-way adapter bracket was the correct size, and the holes were pre-drilled for the right fit to connect to the existing bracket on the (U-Haul Installed) tow bar.

Excellent product, have used for years with no problems.

Another great product from Etrailer. Perfect fit and has held up like new

As the video indicates, ensure that your vehicle wiring is the same as the 7 blade definitions. Mine was not. Had to determine what color wire connections to use for a 4 flat adapter use on a dolly.

Service from erailer is always quick and efficient. The one time an incorrect product was shipped, the company beat a path to my door to get the right item into my hands. Every experience with them has been 100% positive. Great folks!

Great product

The whole staff at etrailer bent over backwards to make sure I was satisfied with the installation of brakes on my trailer. Have made several purchases from them always satisfied with parts and service. Special credit to Jamie great to deal with. Answered all my questions and was very knowledgeable.

These guys are the best! Just about every product imaginable, super service. Obtain alla my trailer stuff from etrailer.

Very high quality plug and wiring. The led lights are awesome

I've had this in use for over a year and they don't build them like they use to. I use this on a gooseneck trailer and the piece of plastic behind the spade connector for the clearance lights and brakes has melted, allowing the spade connector to lose contact with the plug on the pickup. So the lights would cut off in the middle of the night and would have to wiggle the connection till I could fix it. I have an older Hopkins plug and never had this problem. To fix the problem I ended up putting pieces of thin copper wire behind the spade and have done it twice since the plastic melted a 2nd time and once again the trailer clearance lights would quit working. Attached are before and after pictures.

The product works great but the color coding is off compared to the colors on the trailer. I started hooking this up matching all of the colors.( Red on Red, Black on Black, etc.) When I plugged in the trailer in it blew a fuse. So I got online and found out that the Hopkins wiring is different then normal trailer wiring. Overall it works great but the colors should match to make it easier to hook up.
