Jim,

You might want to spend some time in the basement.

If you get under the coach, you will probably find several penetrations using PVC pipe in the bulkhead above the drive axle. Newell used those penetrations for hydraulic, heater hose, and some wiring going forward. IIRC, after the penetrations clear the water and fuel tanks, the wiring and hoses are simply zip tied to the roof of the basement.

Also look in the space in front of the drivers feet for the unterminated wires from the back. Newell ran a lot of wiring for the gauges from front to back.
