YOU DON\'T HAVE TO REMOVE HEADLINER TO REPLACE LIGHTS. THESE PICTURES ARE FOR INFORMATIONAL PURPOSES ONLY TO SEE WHERE WIRES RUN FOR CLEARANCE LITES 73 Canyon Land \" In the middle of the rear harness the clearance light power wire color changes from brown to BLUE, the side markers still have the brown wire. That said on the pulling the wires through the hole to the outside of the coach to make the connection would work on some years - my caps were \"insulated\" with some kind of brown fiber batting, on later years foam insulation was sprayed directly on the cap, so I don\'t know about just pulling the wires in that case.\"
