79 caprice wiring

I have a few wires that arent connected and I just wanted to c if anyone may know where these plug in at..

I have a brown wire running from my headlamp switch to a blk plug that has a orange wire coming from it also, but it runs to my fuse panel. Pic

I also have a red and a pink wire exiting my brake switch from pedal. Where does the red wire run to?

Last but not least I have a clear clip that runs from my steerimg column and just hangs near the columns electrical plugs. It has 20ga Red brown and blue wires in Pic

If u need better pics just lmk...
