Pup: 93 Jayco Jay Series Former TV: 2010 Ford Escape (factory equipped tow package) New TV: 2016 Ford Escape (factory equipped tow package) Both TVs have 4 wire plug. All lights work normally on the 2010, but that vehicle has gone to the resting place of retired vehicles. Plug the Pup into the 2016 and now when I hit the brakes all the parking lights come on, and when the parking lights are on the brake lights are dim. As a test I plugged the Pup in to my father-in-law's truck and everything works as normal. Any ideas?
