It can be done as seen on concrete pumping rigs but most carpet cleaners including myself are not willing to pay the extra cost to have that on the machine.
A simple remote kill switch is simple and inexpensive can be wired into almost any truckmount for under a hundred dollars. Pilot makes a few systems with up to 4 functions per remote/reciever.
Thinking about it, it would be simple to cut off pump, power to the unit, pump out -off or on, and maybe some lights in the truck with just one unit.
Now using the remote to engage ignition is completely different and I would advise against for safety reasons but again-pump on or off, pump out on or off, lights on or off, or engine or shutdown signal would be just an afternoon a remote unit and some wire.
I would just wire everything (on my systems yours might be different) "normally closed" and the is preset controls that are program able into the remote unit for this, so essentially to turn off you just hit the button and it open the circuit and cuts power.
Everything could be bought at pep boys. Now you have me thinking. Watchout! I might just do this to the rig I am doing now.
