And as u can see on that relay pic u sent me, the grey wire is no where to be connected on that relay the only wires that are connected to that relay;

reverse light positive and negative (ground) wire
video camera positive and negavite( ground) wire

i never used relay # 30 to connect pin 17 from the video module, cause i did not know which wire on that harness was pin 17/nor did i know what color it was...

but that does not matter because my vsm works fine wit my navi without pin 17 being connected to the relay
