If there is no power to the circuit board, you need to trace the wiring to see where it is lost. As far as the back up lights, check the switch on the transmission. As far as the signal lights, check wiring. NOT a fun jub, but you need to trace down the wiring until you find where there is power. At that point, check the wire itself for damage. NOTE: Check plugs and even if the wire looks good, always check for continunity. It could be an internal break.
