on a 1966 how do the reverse lights work with a one pin nuetral safety switch , traced the light wires all the way back and it ends up at the fuse box,can't find any other switch to activate the lights,am I missing something here ?

The earlier years with the one terminal neutral safety switch the reverse lights are controlled by a seperate switch either on the column for column shift or at the floor shift.

thanks , just found it,it is on the steering colom as you said thanks
