Installing a 7. When I purchased my 2012 Ford Expedition, it came with a hitch, and a 4-pin trailer connector. There wasn't a brake controller installed, and I needed a 7-blade connector so I could pull my trailer. Adding the 7-blade connector and brake controller was not complicated. www.blueovaltrucks.com
