So it looks like one of the wires in my main headlight plug is corroded/pulled out, I checked out subaruparts.com but couldnt find just that isolated part of the wiring harness.
What are my options for fixing/swaping this out? I am pretty good with a soldering iron and wiring, is there any way to just pick up a new section and splice it in?

Subaru will not sell the connectors alone or a partial harness, you have to buy the complete harness from them.
Your alternatives are a junkyard or auto parts store, depending on what car you have (you don't specify this in your post). Some types of replacement connectors are available in the stores with wire pigtails so you can cut the old one off and splice them in.
