excellent pics . The smaller orange wire needs to be connected or the timer will never advance to shut down. The pic provided by RM shows the orange wire connected to a small spade terminal mounted on the original high limit. Your kit just gives you a jumper wire to complete the heater circuit just like your old part. In that same kit is a small adapter which mounts on the new limit and connects that orange wire.Katie if you look real close at your pic you have the jumper on the wrong leg and their is a big old fat hot wire missing from the pic. That wire may be grounded out and throwing your breaker. Looks like that orange wire has lost its spade clip. The kit comes with a replacement.
