I put the diode on the motion sensor but there is a problem with that. Pin number 7 is an input out source therefore you cannot put the diode on that line. You just need to put one on the blue wire of the shock sensor. Cathode is on the shock sensor side so the anode is hooked up to the motion sensor harness.
