Best 2009 Audi Q7 Trailer Wiring Options


Hi there, Audi owners. Today we're going to be taking a look at the best vehicle wiring options for our 2009 Audi Q7. Here we have our two best wiring options. The option on the left is the one from Curt. And the option on the right is the one from Tekonsha. And in most aspects, these wiring harnesses are going to be basically identical but there are a few minor differences between them and we'll cover those now.This is our Tekonsha harness and as you can see, the module is relatively small, which is nice to be able to fit it into smaller areas.

Versus our Curt, here, which is quite a bit larger. As you can see here on our 2014 Audi Q7, we've got the smaller Tekonsha module installed and we're able to take our wiring and tuck it all up into the little compartment behind our taillight. Whereas, if we we're using our Curt, the Curt itself would take up just about all the space inside of our compartment, here, leaving no place for our wiring, which would require us to have to route it into another location and store it somewhere else, making a lot more work for us.I will say, however, the Curt does have a higher output at five amps on the stop/turn circuit, while our Tekonsha only has 4.2 amps on the stop/turn. They both offer 7.5 amps on the taillights. So if you need that higher output for your stop and turn circuits on your trailer, if you got a lot of lights, big light bars for your taillight assemblies, then the Curt may be the better option for you.Other than that, our harnesses are basically identical.

So you're going to have the same outputs to make the connections to your vehicle, you're going to get length of wire to run it to your battery, you'll have your fuse protection, and they're both going to come with quick splices, zip ties, and sticky pads to get everything mounted up.Now, regardless of which module you choose, you will have to quick splice your wiring into your existing wiring on your vehicle. Both of our modules are going to be fuse protected and they do come with a fuse harness. However, on a Q7, if you have the option to hook it to a fuse panel in the back, it's going to save you a lot of time rather than running it up to your battery. You can purchase fuse taps here at etrailer.com to make your installation much easier.So in conclusion, when it comes to the overall power output, I'm going to have to give that to the Curt because it does have more on the stop/turn circuit. But when it comes to the ease of installation, I'm going to have to give that to Tekonsha because of it's smaller module size.

And this can really make or break it when it comes to the install. If the module don't fit, the whole thing's a bust. So in my personal opinion, I would go with the Tekonsha due to that smaller size.And that completes our look at the best vehicle wiring options on our Audi Q7.
