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.
