Confused on wiring. 1964 Barracuda.

Thanks for the help guys. I don't have a glove box lamp. What's got me confused is that I don't have M-3 either. They took off X-1 completely and looks like they connected M2-A where X-1 was supposed to be. There was no right door switch so it just goes to the headlight switch and to the left door switch, but when I plugged the yellow wire into the door switch, it blows the 20A fuse that was installed for X-1. There's nothing plugged into the socket that goes to the open door lamp indicator or any of the courtesy lights. I'm puzzled as to why they did this. I would have though they'd just leave it disconnected since there's no courtesty lights anyway.
I donoo I guess in that case I'd tape it off and wait til you get everything working and see "what does not work." It is common for various cars to have unused wires and connectors in a harness, for options that "aren't there."
