BLACK/YELLOW Line goes to "Switch Box" on engine side ...what do i hook that up to on the control box side?

GREY goes to Rectifier on engine side ... what do i need to do with this on the control side?

Black/Yellow is the kill wire for the ign. and goes to the switch.
Gray is the sender wire for the tach if you have one.
The other wires fior the auto blend and heat horn do not have to be hooked to anything if you not useing them and for that matter niether does the tach.
