Who knows about turn signal wiring?

Ok, I've taken a look at the wires, here was what I have...purple, green,blue,black with yellow tracer, and black with blue tracer, these are the wires that I used, I believe I used the purple as power up the column and the other four went out to the four corner signals. There is also a black with white tracer, a solid black a yellow and brown that I did not use . Lastly there is a ribbon of four wires together which are yellow, white, black, and blue, these wires are only about 18 gauge while all the others are 16. I did not use any of the wires in the ribbon, if you are correct and the white 18ga is the brake and that is what a should put my 12v brake wire in, will it effect the 12v purple I currently have going in??. The reason I did not use the white or any other of those three in the ribbon is that it was cut off close to the column by the PO of the column ( can't say why?), but possibly because this coulmn has a factory cruise control lever on the signal arm which i am not using not sure how I would access them now? Maybe pull the steering wheel down to the actuator and see if i could pull those wires up the column, extend then and drop back down? But honestly I believe they are for the cruise control which I will never use. So before I start messing with this harness and with this new info, any thoughts??, BTW, thanks to all for the help.
