73 duster electrical

Have a problem here hope you can help me with it. I have a 73 duster that was column shift which i converted to floor shift. I put in a steering column from a floor shift car, my nuetral safety switch does not work and i need to know what to do. Also my charging system does not work, new altinator, new voltage regulator. What gives?
I bought the car years ago , had no motor or trans missing some of the eletrical. The trans harness ,wiper motor harness and starter soliniod were missing, so I bought these items on ebay but i can't figure out were they hook up to even with a wiring diagram
