Best 2016 Volkswagen Jetta Trailer Wirings

A module such as this is absolutely essential when trying to add a trailer lighting circuit to a modern CANbus equipped vehicle. The module itself works beautifully but I deviated from the eTrailer install video for my '13 Jetta Wagon. First, I used the 'poke-n-wrap' method with solder to attach the module's signaling wires to the vehicle wiring harness. I have a personal aversion to Scotchlok or vamp connections because they often fail with time and vibration. This method keeps the harness relatively compact and clean looking, especially if you resecure everything with cloth wiring harness tape. Second, no self drilling screws. I attached the module to the chassis with proper self adhesive tape like 3M VHB. The white ground wire is easily attached to the existing grounding lug on the left rear wheel well, so no self drilling screw there either. Don't poke holes in your chassis with self drilling screws if you can avoid it. I avoided drilling a hole in the spare tire well by running the power wire through the existing body plug in the area aft of the right rear wheel well. It's easy to remove the plug, drill a hole in it, and thread the wire through. Add a dab of black RTV to make sure it's watertight. When powering the module, the suggested method is to split the 1/4" ring terminal and stuff it under the nut that holds the positive battery terminal in place. Instead, I obtained an M6x1.25 nut and secured the fuse holder to a unused, unfused stud on the terminal block inside the underhood fuse block. When it's time to change the car's battery, the split ring will inevitably get deformed and may cause problems. This way, the positive terminal clamp only has to do one thing: hold onto the positive terminal. To bring the wiring harness outside the wagon I went a little off the deep end with a little sheet metal work and Molex MX150 connectors to make the passthrough watertight. I added etrailer 18140 and 18144 to mount the 4-way connector to the hitch so I wouldn't have to fish the wire out of the left-side trunk compartment and shut the tailgate on it every time I wanted to tow.

This wiring kit works great! However the wires were just a tad too short so I had to add extra wire and there were no instructions to be found anywhere on how to wire this up. I used the insctruction video for the Jetta and figured out which wires I needed (but my install was a 2 wire setup not a 3 wire) it took me 4 hours to install but it does work perfectly so it's hard for me to be too upset over the wiring.

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.

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 quality piece. Plenty of length to connect back to the rest of my utility trailer wiring that was still in good shape since it was in an area subject to far less abuse. Nothing worse than having to fix the corroded wires in between replacing the worn out plug every few years. This should give me years maintenance free service even with the toll winter takes.

This is the 2nd one of these I have purchased. They are a good product (therefore the 2nd purchase) but have a few areas that could be improved. 1) In cold northern winters (MN -10 F), the cable gets very stiff, because of the lack of flex, my trailer connection pulled out when turning, dragged on the ground and ground down the plug. 2) the connection where the cable jacket meets the plug separated (again, due to cold weather?). Even though I would prefer a more temperature-forgiving flexible cable, I believe this design is better than the other 4-flat trailer-end wiring harnesses currently available. I also purchased a Hopkins Endurance Quick-Fix Replacement 4-Way Flat Trailer Connector w LED Test Lights - Trailer End to as a quick fix to this cable to temporarily fix my trailer wiring until permanent repairs can be done.

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.

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.

This was used on my 2009 Jetta sports wagon, and it did the trick!

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.

Great product no issues at all. Product as described & fit properly.

Pretty straight forward. I used it to switch my European trailer's connection to be able to connect to my Wrangler's 4-pin trailer hookup. No issues. works great.

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.

I was super impressed with the service from etrailer.com! The product was just what I wanted, price was great, and I received it in just a few days.

Exactly what I needed. Etrailer always comes through

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.

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 was expecting blade connectors as shown in the pictures and video and that is the main reason I purchased this item. Instead it had screw connectors.

It would have been very helpful if the item description would have stated that the trailer connector was equipped with "Spade Contacts" and require Spade Connectors, and/or illustrate this in a picture, and provide those connector as part of the package. It would have saved a lot of time in making a second order to acquire the Spade Connectors.

Not installed yet but looks as good as one used before in a former vehicle. The actual adapter I received is "Reese", which is a reputable brand for towing accessories.

Good quality and everything needed for install in my 2006 Honda Odyssey. Now I can easily tow with either a 4 wire or 5 wire since the harness retains both.

High quality with nonoxiding metal parts. The extended length 4 pin connector makes hook ups a dream.

Works fine. Reasonable price. I'm happy that etrailer is around.

They have just what I needed and it arrived very quickly.

I have used etrailer probably four or five times now and have been very happy. Shipping is fast, prices are reasonable and the products are of good quality. I purchased more of the Quick Fix 4 Pole Trailer Ends - they work really well for the non-automotive industrial control project I am working on.

This cord has much better connector than most with two sided connectors, most plugs are one sided and just don't connect over time.

As usual with E-Trailer, the connector cable that I needed arrived quickly and was the right part. When I had a question about my toad wiring, they responded with an answer and an instructional video which solved my problem. Their customer service is exceptional and I will continue to do business with E-Trailer.?? G. Rusk 2007 Fleetwood Terra LX 31-M. My toad will be a 2007 Dodge Dakota FWD.

I recently had a need for the Hopkins Endurance Quick-Fix Replacement 4-Way Flat Trailer Connector w LED Test Lights - Vehicle End - HM48190 to replace the faulty one on my van. It was easy to find what I needed on the site and the price was comparable to other sites I had visited. I decided to go with etrailer because I had previously ordered the hitch through them. I appreciated the fact that an email was sent out confirming that they received the order as well as a follow-up email telling me that the part was shipped along with providing the tracking number. The installation of the part was easy and took no time to complete. Overall it was a fine experience and if I need to order anything in the future, I will be sure to come back and order from etrailer.

Great product. Easy to install

Works really well.

This product wooks great. I will do business with this company again

Used on a pull behind motorcycle trailer so could go from receiving a 6 pin to a 5 pin. Wired it into loom so can use on more than one motorcycle. Works great. Glad to have found a place that even sold this product.

A similar trailer light connector was installed on my motorcycle cargo trailer when I purchased it way back in 2003. When I purchased my new Gold Wing in 2019, I wanted to use the same type of connector. Since I had to add a new female connector to the bike, I decided to renew the male connector on the trailer. I especially like this connector because it always stays secure when connected. I also wanted the connections to be out of sight when not in use. I have pulled my trailer with this new connection for over 2,500 miles and it has performed great.
