Question:

I search YouTube uhual and etrailers site for a guide of some kind for the wiring harness for my 2013 Audi A5. I’m sure on the wires to connect for my turn signal lights since I’m playing on towing a small trailer. I was lucky enough to find a video on how to install my hitch from this site thank god but I’m stuck on the wiring help please.

When installing a universal trailer wiring kit like the Curt Powered Light Converter Kit # C56190KIT the best thing you can do is simply test the wires behind the tail lights to ensure the correct functions when splicing into them with the harness. I wasn't able to track down specific wire colors for your Audi, but even when a diagram is found it's still always best to test them, as vehicle manufacturers tend to switch up wire colors without notice at the factory.

You will need to use a circuit tester like # PTW2979 to test the wires behind the light assemblies to see which ones only gets power with the running lights activated and with the brake lights activated on the Audi (it sounds like you already figured out the correct wires for the turn signals).

I wish I could give you a more clear cut solution but this is going to be your best option for installing the trailer harness.
