TR3A brake light switch

[Popnglo@aol.com]

The brake lights have stopped working. Wiring is fine, I can connect the two 
leads coming off the hydraulic switch, located on the 5 way connector and the 
lights go on.
I've replaced the switch twice, so the possibility of two switches bad are 
questionable (but possible, I guess). I bled the system. 

Is it possible that the 5 way connection has some blockage that reduces the 
pressure to the brake switch? Any suggestions?
