I'm in the middle of installing my new wiring harness on my 55.2 12 volt. As I've gotten to the wires coming from the turn signal switch on the column, it's obvious they are in really bad shape and I'm contemplating replacing them due to how worn they are. I've done some searches on Stovebolt and goodle to attempt to try to figure out:

1. What kind of turn signal switch I need
2. How I got about replacing them.

Here is my column: https://flic.kr/p/aUmwhX

Any help/advice is appreciated on this.
