I have a utility trailer with a 7-way connector. My 2001 has a factory installed hitch. I found the taped up wires behind the bumper.

How do I match the colors?

The white tape with the info is to weathered to read.

Red Battery Power
White Ground
Brown Parking Lights
Dark Green Right Turn Signal/Stop Light
Yellow Left Tuirn Signal/Stop Light
Light Green Back Up Lights
Light Blue High mount Stop Light

Thanks. I plan to hook it up later this week for next weekend.
