i put my sled back together today and the lights dont work. should the rectifier at the left foot be plugged in and to what. my guage lights dont even work.

ok i found a four way connector. it has 3 females and one male but the regulator only only has one male and one female. is this where it plugs in, or should i just plug er in and try it. i was sure i seen the tailight on this afternoon.
