Need some help with electrical connector.

Hello first post and new to the site. I own a 1973 duster that was untouched from a farm around 1983. It had the usual ammeter damage to everything and the wiring was pretty hacked to include multiple radios. I have a few wires I am attempting to track done.

1) First is this connector with 2 orange and 2 yellow
- it has power with key off on the yellow side if correct.
- I am completely unsure where it goes ( it is not showing on any of my diagrams.

2) on the fuse block I have attempted to locate my stock radii wire but cannot locate one anyone got a picture of their original plug ( 2 orange/white/red?
