I need a little help understanding the instructions for modifying the RS49-425 PIR. On the diagram of the circuit board for the RS 49-425 PIR, It states "solder one side of relay coil to battery negative. Anode of diode too." Does this mean solder a wire from the relay coil to the battery negative and then solder a small wire from the battery neagative to the anode end of the diode. Also it states solder one side of relay coil here and cathode (silver band) of diode" I don't quite understand these instructions. Do you solder a wire from the relay coil to the IC 2 pin and then solder a wire from the IC PIN to the cathode end of the diode.This is my first attempt so this will not likely be the last question I ask.
