Review on Hopkins 47775 Simple Control Connector by Stephen Doyle

The electrical circuit on my truck was upside down, but I already knew which corner the brake light wire went into. It is best to connect a free cable to the car first and check the rear brake cable. It can be difficult to remove and replace if you make a mistake and put it in the wrong slot that you need. Wire colors vary by vehicle, most are blue after connecting the car to the rear brake of a trailer or van. I saved a lot of time to route a wire or connect a bunch of wire harnesses in a car. plug and play
