Recommended Trailer Wiring Harness For A 2020 Audi Q3  


I will be ordering a hitch to install for a customer, but I also need a trailer wire kit for this 2020 Audi Q3. Can you recommend a part number so I can place the order? I will be installing DT68MR hitch. Max w/Steadfast RV Service

When installing a trailer wiring harness on your 2020 Audi Q3 The ZCI Circuit Protected Vehicle Wiring Harness w/ 4-Pole Flat Trailer Connector and Installation Kit # 119250KIT will work for you. This harness will bypass factory wiring and involves no cutting, splicing, or plugging into vehicle's wiring.

This kit works with 2-wire, 3-wire, PWM, and multiplex wiring systems. It has a maximum amperage of 4.2 amps per circuit on the stop/turn lights and 7.5 amps per circuit on the tail lights. It also has a built-in tail light converter.

When installing I would recommend putting a small amount of grease on all electrical connections on the 4-pole connector to help prevent corrosion like The Dielectric Grease for Electrical Connectors, 2 oz. # 11755.
