Question:
Hi eTrailer Team, I own a 2024 Audi Q3 Sportback 40 TFSI quattro and already have a 2-inch hitch receiver installed. I use a Kuat bike rack with integrated LED lights and need to connect its 4-pin flat connector so the brake lights, turn signals, and running lights work properly. My vehicle currently has no trailer wiring installed. Is it possible to purchase just the electronic wiring harness and converter module, without having to buy a complete trailer hitch or tow ball kit? I’m particularly interested in a plug-and-play solution, or one that doesn’t require cutting into the vehicle’s factory wiring. Could you please recommend the most suitable kit for my specific Audi model and confirm whether it is compatible with its electrical system? The vehicle is a Mexican-market model. Thanks in advance for your guidance! Best regards,

Hey Roberto, we can definitely help but we do not have an plug and play trailer wiring harnesses that fit your 2024 Audi Q3. You would have to hardwire in a universal 4-way like the Curt # C59236 and you'd have the trailer wiring needed for your Kuat bike rack. Which rack do you have? Is it the Piston Pro X # KU98VR?
