I need a wiring diagram

I need a wiring diagram for a 1994 Atlantic Home. I have hud numbers TEN24 6839 and TEN24 6840 and the serial number 21-94-978-6383 there is also an A & B behind the serial number. Date of manufacture is 11-12-93. Please help we have some lights that are not working and need to know where to start.
thank you,
