No, flash to pass should do nothing wrt brake circuit.  The brake  
lights should function at any time, though.  Basically, I'm not sure  
if the brake light switch is supposed to be positive or ground (I  
believe positive).  Basically, I would just make sure that the  
circuit is fused and figure out the proper routing.

Good luck.
