How to wire the electric one wire kickdown or shift down on a non computerize engine set-up?

A th375 is a th400 with a small tail shaft same as a th350. Uses a th350 small yoke. The kick down is electric like a th400. Use a switch(pedal or cable operated) and 12 volts to energize the kick down solenoid.
