Aside from the nightmare of the installation. You would need a Timed signal source to go to the VSS (vehicle speed signal) input wire to "fool" it into thinking the vehicle is running (wheels turning) The frequency of that signal would determine the engine speed.
Since it says it takes a sine or square wave input, a simple circuit to produce the appropriate signal can be made easily. That circuit could have a potentiometer on the dash it to vary the frequency and then be able to have variable high idle RPM
Since it uses a tachometer signal to shut off the unit if the transmission is accidentally knocked into netral, you would leave that wire disconnected.
(never did like installing them due to the mechanicals. Just my weirdness, I guess.. I put one on my Motorcycle and it works good.)

Get a electric door lock actuator or rear hatch actuator and mount it to the fenderwell, it needs alt least 3/4 to 1 inch movement. after all, we are really only looking to go to 1200 rpm or so.
Make up a cable bracket like the cruise control.
find a motorcycle cable to operate between the door lock actuator and the throttle cable end with a adjustment screw that is already on the motorcycle cables
Hook up the cable at the throttle end exactly like shown in the Magnavox instuctions The cable has to have enough free are (no sheeth) and slack to ensure no interference with normal throttle.
Use a dash switch to activate/deactivate a latching RELAY. wire up another relay to the Brake wire to disconnect the latching relay power if the brakes are depressed. (brake wire availabe at the connecter and harness for trailer controls)
Add another relay to disconnect power if the trans is anywhere but in park.
