  My '85 Nissan truck has something similar. I think most cars do. FWIW my
'70 Plymouth Superbird did the same thing but much simpler. They simply put
a electrical solenoid on the side of the carburator. With certain
accessories (don't remember which ones) were on, power was applied to the
solenoid and it's plunger raised up about 1/8" and pushed up the arm
connected to the trottle on the carburator. Very simply and effective.
