We have a 2002 f150, we took towing (7pin plug apart to replace it) assuming all replacement plugs would be the same . however apparently not. we did not write down what color wire functioned as what ( blue for brake, red for stop etc.) can you tell me what each color is for ??? we have , white, blue,brown , orange, green,yellow.

the lines where for a 2002 trailer.



good luck the lines where for a 2002 trailer.

good luck

oh yeah, it has a 4-pin counterpart but they did not disclose any information, just the 7-pins oh yeah, it has a 4-pin counterpart but they did not disclose any information, just the 7-pins

For 7 pin wiring for trailer pin blade plug is:
pin #1 is the White wire = ground or common.

pin #2 is the Blue wire = brake control

pin #3 is the green wire = tail lights,marker lights & license plate light

pin #4 is the Black wire = battery charge to trailer

pin #5 is the red wire = stop/left turn signal

pin #6 is the brown wire = stop/right turn signal

pin #7 is the yellow wire = extra aux circuit power


3 Pins are only
1- 12 volt power

2- Back-up lights

3-Trailer brakes

Plug connectors normally have the pin number and the wire color molded
in to them next to each connectrion point but can be fun to read.
