CURT 4-Way Wiring: Ford Edge, Escape & Mazda CX-5 Fit Guide
Adding a 4-way flat trailer-light connector is easier when the harness matches the vehicle's actual taillight wiring. CURT makes different custom T-connector kits for Ford Edge trim packages, Ford Escape model years and Mazda CX-5 generations. Match the year and trim before ordering.
Start with the vehicle, then the harness
Ford Edge
2015–2018 SE/SEL: CURT 56272. Sport/Titanium of the same years: CURT 56292. Trim package determines the correct listed part.
Ford Escape
CURT 56335 covers listed 2013–2016 trims. CURT 56320 covers 2017–2018, excluding SE. Don't assume every year/trim uses one plug arrangement.
Mazda CX-5
CURT 56310 is listed for 2016, while 56377 covers 2017–2021. Model year is the primary distinction in this pair.

Four installation checks
- Confirm the exact model year, trim level and taillight connector arrangement using CURT's vehicle application data.
- These custom kits supply a 4-way flat trailer-lighting output for running, brake and turn lights; they do not provide an electric trailer brake controller connection or 7-way RV socket by themselves.
- Where specified by the kit, run the fused power lead to the vehicle battery and secure the converter and ground connection according to the manufacturer.
- Follow the vehicle's towing limitations and CURT's installation instructions. Test the trailer lights after installation, and never assume adjacent years or trims use the same harness.
The four trailer-lighting terminals perform the same basic functions, but the vehicle-side T-connectors and powered converter are not necessarily interchangeable across applications.
