Help with furion back up install....

[Chad1383]

Hello everyone, I have a 2021 Montana 385BR and it has the plastic cover on the back for a back up camera install. I pulled the cover off and there is no wires for me to grab and hook up. I do see a 14/2 romex wire but it will not budge at all, nor should I be using that hook this camera up. Any help is appreciated, my past trailer the wire was right there to use.
