I think I have a short.. How does it get fixed?

Wow! So I plugged the ground wire back into the terminal, and everything is working again! The headlights (that I thought the bulb blew) now work, turn signals, brake lights, everything! I have no idea how the two are connected, but it somehow fixed it!
 
Apparently its the ground for all of the lights.

Keep an eye on things in that area.

You really shuold do the fog light rewire I showed you. It will save you from revisiting the mfs later on.
