Need Wiring Diagram for 1999 Coachman Catilina

i've been doing some repairs i i took pics of the junction box where all the wires were connected but after i took them apart there are two wires i'm not sure where they go. Most of the wiring i think go to the 7 pin connector and but there are more wires and i no sure what they connect too.

its a 31 Ft Catalina 299TB and its a 2000 not a 1999

The schematic or diagram you seek probably never existed.

Need more info. I looked up Catalina and got MH,TT, and 5th wheel.
I had a 1999 Coachman IKS, 36 ft. 5th wheel.
It had 12 volt from the front truck plug to the Marker lights and 12 volt B&W colored wires from the Converter to the OH lights and 120 volts to the receptacles. It also had RG59 TV cable run from a splitter in the entertainment center to the front TV point. One more circuit for the slideout. I no longer have the RV.
