I bought a used 98 TJ. When closed, the tail gate pushes a small push button switch on the Drivers side. It is a grounding type-like you find for add-on alarm systems. I cannot find a switch in any Hanes manual of the wiring diagrams. I follow the wire to/by the kick panel/dash area drivers side where it just ends cut/no terminal, so I know it is doing nothing. I was wondering if there was any models that a switch that would make the dome light come on with tail gate open?
