Fixing some of the wiring on the Ford 550 TLB. So the TLB has full cab, rear work lights, rear id lights (red up top) and rear marker / brake lights near the center of the cab.
Has anyone seen this setup? The work lights and id lights work. The center lights were wired to the side flashing lights. I fixed that but now I am lost has to how to wire the rear lights. The harness has a brown, a white, a red, and a green wire in it. This harness comes thru the floor near the hoe controls. Also under the dash there are two brake light switches. One brake switch has no wire and the other has 2 yellow wires attached, one has power key on.. My manual does not show the rear lights or any brake light switches. These may have been added but I am not sure. Any help thanks in advance.
