Anyone know where the light-green (CHMSL = center high mount stop lamp) wire is located on a 2011 F150 for wiring the 3rd brake light on a camper shell?
I found the following for 2004-08 models, but I just see the wiring harness on the 2011 and no light-green wire:
"The CHMSL wire on 2004-08 F150s is located on the driver's side frame under the front door. If you look under the truck at this location there is a plastic shroud around factory wiring/plugs, on the outside of the frame. At the front portion of the wiring there is the light green CHMSL wire wrapped onto the cluster of wires."
