They say connect red to red,blue to blue,and green to green.But for anyone going to install the trim the red goes to a purple and the rest are the same.The red would connect to a positive wire, or a positive at the breaker panel to provide the trim switch to be active all time. Purple is hot with the key on. By connecting to purple, it will be active with the switch on.JohnJones Trolling Motor Services870 773 3474Motorguide/MinnKota/PowerPole/Lowrance/Humminbird
