[64Overlander]

I just finished addressing the exterior lights on my 64 Overlander. They all work including the electric brakes which I just had replaced. The interior lights run if the trailer is hooked up to the truck. If I hook up a battery in the rear compartment only the kitchen fan and the water pump work (not for sure where it is yet). The original uni-volt is missing. Does anyone have a picture of their rear compartment with all electrical components present. I am currently trying to reconstruct mine to determine which appliances currently work.
Thanks
