Installed LED tail lights and cruise is not working
Answer: When using LED tail lights, the violet wire at cold side of brake will not
read ground through the brake system. A five function relay will be required to let
the violet wire read ground and then lose ground when the brake is applied. Connect
the relay using the selected terminals below:
85 to cold side of brake (+12 when brake is pressed)
86 to ground
87 not used
87A to violet wire from cruise harness
