Ok. Turned on markers to make sure test light works. Good there. I have no power to the wires that feed the scare lamps. I am trying to trace to a possible switch problem. The left secuity lamp works from switch panel and switch in tank drain area. NO POWER THRU THE WIRES TO THE REAR LAMPS. I wanted to find a wiring diagram for the whole unit. None to be found.
Are you talking tail lamps or the interior lights? For the interior, look under slides or behind the furniture for junction boxes. They may be tied in there and the connection has come apart.
For the tail lamps, there are generic wiring diagrams that might help.
I recently had one of my rear wall lamps not working right. Found the button switch was the problem. Managed to replace the switch with one from an OEM vent fan I replaced and saved some parts from.
