tech ? clutch pedal switch

hey guys & gals, as some of you know i've been fixing my 71 duster from a hit & run and almost there (not enuff free time) so you guys know i replaced front clip and 1 inner fender , so i pulled motor and tore out dash cause i kept finding stuff the orginal owner had hide or just tore up, like under dash wiring. well got that fixed , but today when i wet sanded and buffed out paint ( looks good. wet sanding scares me) i went to get dash gaskets all installed and new boots when i noticed a switch with a wire cut coming out of clutch pedal inside, this has to be a neutral safety switch right. it's a little round kinda switch , i know i can solder new wire to it , but where would it run too? help! i always depressed clutch when starting anyways so i never noticed if it would start in gear. i should be in shower but girlfriend doesn't know i'm in my office online. oh here's porgress to date.
