I am trying to put a manual switch for the back up light so I can get some light when working under the trailer. But I don’t see any fuse marked as back up light in the dash fuse box. Is that controlled by the lcm computer? I know I can splice the wire directly from the transmission sensor but just looking for a simpler solution.
Another thing I don’t see a fuse for the back of the cab light. Any idea where to look?
