That was like reading a four year old German kid's Christmas list, I didn't understand a bit of it.
Anyway, if the brake switch wiring is exposed and making contact, the lights will come on. You won't burn anything or cause any damage. Also, the switch is fully adjustable using the two locknuts to move it fore and aft to set it properly so that minor pedal movement will engage it. Tape the wiring up and readjust it until it sits right. #2 and 3 in your diagram are part of the switch and shouldn't be messed with unless you like breaking apart a good switch and making it useless.
