I have a 2005 F-150 Super Crew. I recently purchased a Raider truck canopy for it. The canopy comes with equipped with a brake light. The place I bought it from is having trouble getting the brake light wired correctly. On their first attempt the light came on when you stepped on the brake but when you signalled left the light on the canopy flashed. I took it back to them and they fiddled with some wires and now the light comes on when you step on the brakes but when you signal right the canopy light flashes.

The place I bought the canopy from is now saying they need to contact Ford and get a wiring diagram. They are looking for what they refer to as a CHMSL (Centre High Mounted Stop Light) wire.

Does anyone know how I can find the location of the CHMSL wire so they can wire the canopy correctly?
