My 2018 SQ5 has the oe hitch and harness option. Can you tell me how to disable the rear proximity sensors when the harness is plugged in? I want to use the corresponding male plug for the oe socket and an aftermarket plug for the trailer end.

Typically when a vehicle has the rear proximity sensors there is a way to disable them when towing a trailer. You might either have a tow mode that disables it or you might be able to do that manually. If you check out your owner's manual it should give you some insight into this.

Hi, what would I need to install a 7 pin harness in a 2018 Audi Q5? Is the installation much different than this kit?Thanks

This installation kit is a 4-way trailer connector for the 2018 Audi Q5. If you need a 7 pin you will need to install this 4- way connector in conjunction with a 7-way kit part # ETBC7. The ETBC7 comes with the 7-way plug, duplex wire, hardware and circuit breakers needed to complete the installation on your 2018 Audi Q5. I have attached installation instructions below.
