[Chevelle-list] TH-400

hi, another question on the TH-400 kick down mechanism,
so the gas pedal controls the switch, but where on the trans does it hook up??
i looked at my trans and cannot find any kind of plug- or electrical connection. the oil pan says "hydromatic GMC" does this mean it came from a truck ?
there is a vacume switch on the passengers side of the trans- but thats it

thanks
Harlan
