neutral safty switch?

Hi, What due you mean boot? if you are refering to you lamp connector yes this will make you back up lamps not work, Back up wire color code should be black with a tan tracer this is your back up lamp wire, wire to your back up sockets in the trunk should be violet and the housing is the ground.. check power to that wire with a test lamp.. if there is no power check power from the switch ... Not sure but i think that on of the end terminals of the switch is you back up lamp signal... Good luck and let me know if i could be of more help... Thanks Ricardosdemon72
