Old Wiring Tear Out

Getting down to the end of the last bit of tear out. There are three separate wiring systems in Airstreams: 1] The wiring harness for running and tail lights, 2] A 12 volt DC system and 3] a 110 volt AC system. I tore out the AC and DC wiring which is this heaping mess as seen here.

I've already started drafting wiring diagrams for new systems which I'm actually looking forward to installing.
