2018 Audi Q7 Brake Controller Installation


Hi, looking for what is needed for an Audi Q7 break controller and witrriing for a 7 pin connection to our trailer. Can you please advise.


Expert Reply:

If the Q7 has a factory 7-way socket you can simply plug in the Curt Echo brake controller # C51180, pair it to your smart phone and you're done. The Echo installs in your trailer connector so there is no bulky box to get in your way inside the car. Please check out the included video.

But if you have no wiring you'll need to install a basic 4-pole harness and an upgrade kit to convert that wiring to the 7-way format required for the Curt Echo.

Available 4-Pole kits include both a hardwired type # 119190KIT and a non-invasive no-splice Zero Contact kit # 119250KIT which uses magnetic sensors instead of direct wired connections to obtain signals from the car. Install videos showing an Audi are linked for both kits so you can decide which you prefer. The wired kit costs less but the ZCI requires no permanent modifications. Either one will work. You'll then convert either of these 4-pole kits to the 7-way format using part # ETBC7L.
