4-Way to 7-Way Adapter for 2015 Audi Q7

Question:

I have a 2015 Audi Q 7 and I need a 7 way to 4 adapter. I currently have incandescent bulbs on the trailer, but may switch to LED. What adapter plug should I get?

Now if your trailer does not have brakes all you would need is the part # 37185 as an adapter to convert the 4-way to a 7-way.

If you do have trailer brakes you would need the # ETBC7 instead of the # 37185 and a brake controller. This kit comes with everything needed to wire up the 7-way and install a brake controller.

For a brake controller I would recommend the Prodigy P2 Brake Controller part # 90885. This is one our best selling brake controller because of how well it works and how easy it is to setup. It has the most advanced inertia sensor which provides a proportional amount of braking power to the trailer brakes.
