Question:
Hello Looking for wiring kit for our 2020 Land Rover Discovery Sport. We have installed the hitch but am now struggling to find good options for wiring. Need a wiring kit for a brake controller and lights. Curious if you have any options that would work well in this application. Thanks

Hey Scott, thanks for reaching out!
I have some recommendations for you, but nobody has a custom wiring harness for your 2020 Land Rover Discovery Sport so we'll have to get creative with the parts we use, especially since Land Rover vehicles tend to have more sensitive wiring.
For your application I recommend the following parts:
- ZCI Circuit Protected Vehicle Wiring Harness # 119250KIT
- 7-Way RV Upgrade Kit # ETBC7L
- No-Drill Mount Bracket # 18136
- Curt Echo In-Line Bluetooth Brake Controller # C79DR
The ZCI wiring uses a special clamping system to determine when to send power to the different trailer light functions so you don't have to cut into your OEM wiring, and then the Upgrade Kit and Echo In-Line controller install at the back of your Discovery Sport so you won't have to install anything in the cab of your vehicle. Once the controller is installed you'll use the app to adjust your settings and be good to go!
