51 concord stop light switch
 

just picked up 51 concord, problem is the brakelights/ turn signals dont work. previous owner installed a "its a snap" harness kit. cannot find location of original stop light switch, everything i have researched shows a hydraulic switch from factory, but nothing on the lines. any ideas where the switch was originaly located??

The original switch was mounted in the brake line on the outside of the left frame rail towards the rear of the car.
