Outdoor TV wiring harness

[Slow ride]

Hello,
I recently purchased a new to me 2005 Expedition 35m. I found the coax cable for the third/outdoor TV. This harness also has a red, a black, and an orange wire wrapped together. I assume (but not sure) the red/black are 12 volt but I am not sure on the orange wire. Any insight on these other wires would be great. Also does anyone know how I could turn the outside outlet (in the bay) to run off the inverter instead of shore power only?
TIA
Eric

You are probably correct on the 12 volt wires being the black and red with the orange being hot for the radio memory. As for getting inverter power out there, you'll have to pull a Romex cable from your inverter circuit and add another receptacle.

Thanks for the info. Another project to add to the list.
