Question:

Hi I have to replace the 7 blade connector due to it hitting the ground and stripping the wires on a steep turn Can you tell me the color mapping of the 7 wires? Ground, left, right, reverse, aux, tail and brakes?

The wiring colors from the Curt T-Connector # C56357 will be the following:

Black - 12V Power
White - Ground
Blue - Brake Controller Output
Red - Reverse
Yellow - Left Turn/Stop
Brown - Running/Tail Lights
Green - Right Turn/Stop

My contact at Curt confirmed this for me. If you don't already have a replacement 7-Way then you can use the Hopkins Endurance Quick-Install 7-Way Trailer Connector with Universal Pigtail Harness # HM47210 which has the following wiring configuration:

Red - 12V Power
White - Ground
Blue - Brake Controller Output
Purple - Reverse
Yellow - Left Turn/Stop
Brown - Running/Tail Lights
Green - Right Turn/Stop
