TCC Brake switch conversion??

[69TA]

Thanks 130fe. I am using the brake switch from my 94' Formula LT1 parts car. I already have it hooked up in my 69'. I have the orange & white wires hooked up like factory which allow my brake lights to work. There is one solid light blue wire that plugs in with the orange & white wires that is on the switch. I have the light blue/black stripe wire hooked to my TCC switched feed wire and the pink one I have on a switched 12v.

I basically was wondering what the light blue wire was for but didnt want to make this sound confusing.
