Today, we're going to be taking a look at the Tekonsha upgraded ModuLite trailer wiring kit, along with the Buyers trailer adapter on our 2014 Audi Q5. Now our Tekonsha wiring is going to provide us with the 4-way trailer connector. However, a lot of people have trailers that have a 7-way on them. And that's where our Buyers adapter going to come into play. The adapter is going to give us a 7-way. So we'll have all seven functions like our tail lights, brakes, turn signals, reverse lights, and we even have the option to put in a brake controller and have a 12 volt power source.But the nice thing is, is we still get that 4-way on the outside as well.
So we'll have a dual connector here. That way if we have two different trailers, different connectors on there, or if we just tow several different trailers, we'll be able to hook up really easily. Now I do want to mention that this is a pretty common thing. People want to be able to use a 7-way on their Audi. However, the Tekonsha wiring is meant to stay on the inside of the vehicle.
So the problem comes up to get that wiring outside, so that we can mount up the 7-way.But our Tekonsha wiring is going to be stored on the inside. The converter box and everything else is actually right behind this panel here. We just pull that panel out of the way. We can see we have our converter box and all of our signal wires hooked up. Now the converter box is going to take the signals from our factory wiring, and convert them into a working signal for our trailer.
It's also going to make sure that there's no feeding, and it's going to protect our factory wiring from any kind of potential issues that may be on the trailer end.Another thing I really like about the Tekonsha ModuLite here is that it is fuse protected. So we don't have to worry about overloading our taillight circuits or turn signal circuits from our trailer wiring, because it's going to have its own power source, that we're going to have to hook directly to the battery. And our Tekonsha wiring is going to plug directly into the back of our Buyers adapter so that way we're not going to have to worry about cutting or splicing anything on that end.That way we get all the signals coming out of our Tekonsha going through the adapter, coming out to the 7-way, and we can have it right by our hitch ready for us when we need to tow. Now I do want to mention, typically our wiring is not going to be installed in this area. Most people are going to be installing it on the hatch, because that's where the lights are.
But again, the problem arises when you want to put a 7-way on your vehicle, you have to route the 4-pole wire somehow down the hatch, down the body, and then get it out to the outside. But I found a much easier way.So if you are going to be installing a 4-way, you can still do it right here. Or if you're going to be putting a 7-way on, it's still much easier to install it this way. And we'll give you a few tips and tricks of how we got everything in place, just to make it that much easier for you. In fact, let's go ahead and do it together now.To begin our installation, we want to open up the rear hatch on our Audi. And we're going to be removing the floor coverings as well as the spare tire. So we can pull up, set this panel aside. And then we'll pull that spare tire out. Now before you go to lift it up, you want to disconnect the electrical connector here. There's two squeeze tabs on the side. We'll pull that out, and kind of just help guide it down through the wheel. So it doesn't get caught. Then you can lift up this piece separately, set it aside, then we'll grab our spare.Now right underneath this panel here is our battery. So we'll lift up on this cover. Just kind of tuck it out of the way. And we'll have these two tabs here, press away from the back and that'll give us access to our battery. Now, at this point, we need to start testing our wiring for our taillights. Now you'll notice that the taillights are on the hatch of our Audi and not on the body. And it is going to make it a little more difficult to test it because typically we would have to pull this panel down to get to the back of the connector, but I already did some checking, and I followed all the wires and they actually come down into this area right here.If we grab this panel where our 12 volt outlet is, let me just pull away. Now, you do want to be careful because that 12 volt outlet kit is on the back, so we'll just rotate it out of the way. But we have this big bundle of wire here. And we already went through and tested which wires are which. And we can go through and let you know which ones are for
2014 Q5
Great video. This method is way better than snaking wires up the tailgate like other videos.
Took me less than 30min. Removed the panel, located the Tail and Left/Right turn wires. Soldered all connections. I Used the power source from the 12VDC socket (20amp) in this panel (which will not provide power to the trailer lights with the ignition off such as the hazards). I just didn't want the converter powered 24/7. Plenty of anchor points for the ground inside that panel too.
This worked perfectly on my 2016 Q5. I confirmed the wiring was the same colors. So much better than having the wires in the door.
Many thanks for posting this video. I want to put a hitch on a 2015 Audi Q5 and was dreading to wiring install based on other videos. The process documented here is so much less work !!
We're glad the video was helpful!

Fantastic video. Is there more as to where and how the full seven wire connector gets installed to the cabs brake controller.
Thanks for your video ! I followed it on my 2014 Q5. It works very well.
Outstanding! If there is anything else you need make sure to use the fitguide on our home page! www.etrailer.com/
@@etrailer Thanks ! It turns out I need a brake controller, I've ordered C51180 from your website.
Hey was wondering for the 7 pin, if we do want to hook up the black 12V, do we just run a wire to the battery terminal and that's it?
You will want to run a wire to the positive post on the battery in order to get power at the 12v pin on the 7 pole. Check out the following link to see our very popular 7 pole kit to use with the 4 pole kit in this video.

HEY! Maybe you can help me. I'm having one issue. After a braking the blinkers stop working on the trailer/test equipment. I'm seeing It's a grounding issue, but for the life of me can't seem to figure it out. Given it's happening on the tester, it must be in the audi. Any ideas? I did what you and several other videos showed which was to ground it to sheet metal. I've done it, and in several spots. Unfortunately, the results are the same. The blinkers in the tester/trailer stop working after breaking.
You may try grounding the control box to the battery with a jumper wire. This will tell you whether or not it is a poor ground.

Also was wondering, what size fuse for the black wire going to 12V on the 7 pin , also a 15amp?
If you install the ETBC7 kit that we recommend, it will come with 3 heavy-duty circuit breakers that are 20, 30, and 40 amp.

avez vous les couleurs de fil pour mon audi q5 2011 merci
I installed this on my 2015 Audi Q5 2.0T about 2 years ago but never used it. Now that I need to, the lights don’t work. I opened everything back up and confirmed all of the wiring is correct, no fuses are blown, and it all seems to be good. Can anyone help me troubleshoot. eTrailer support wouldn’t help other than telling me to buy the “latest” version.
Based on my experience, the convertor box has probably died. I suggest buying a new one and installing.
Do u think it will work on a 2011 q5 3.2
The Tekonsha # 119190KIT is not a vehicle specific item, it'll fit just about any vehicle. It'll work just fine on your 2011 Audi Q5.

Why wouldn't you just tap into the 12V supply line going to the 12V supply socket instead of routing a wire directly to the battery?
The manufacturer does not recommend connecting the power wire to the 12V outlet because you run the risk of overloading it and blowing the fuse. This cause you to lose functioning of your trailer lights. Connecting it directly to the battery will allow for no interference with getting power to the trailer.
