Adapters Wiring | etrailer Trailer adapter converts a tow vehicle's 7-pole wiring connection to a 5-pole flat pin connection for towing trailers with hydraulic brakes. Coiled cord stretches and contracts for extra flexibility. Threaded bracket ensures a secure connection. 7- and 4-Pole Trailer Connector Socket w/ Mounting Bracket There are a couple of trailer wiring kits that are designed for your 2015 Audi Q7. If the trailer has a 4-way connector and you have no need for a 7-way connector I recommend part # 41155. This just plugs into the connector at the rear of your Q7 behind the bumper. If you want a 7-way and 4-way connector then you could use part # HM40975.
