Ford 7 Pin Trailer Wiring. They connect the taillights, brake lights. Also I have a Reese brakeman compact.
The connector is in a rubber plug, and will slide down and out of the mount. Refer to your trailer service manual and plug installation instructions to avoid wiring problems that may damage your trailer, brake controller or vehicle! Anyone have a diagram of which pins supply which functions?
The left and right turn signal lights should each have a different color.
If so, I need to get that fixed.
The Tester is designed to indicate a faulty wiring or blown bulbs/light in the wiring on your trailer, caravan or horsebox with a Six Light LED system. They connect the taillights, brake lights. Cut the four-pin plug off of the trailer harness.
