I bought some wire and a cheap on-off latching anti vandal switch, if you unplug the connector in the back you can wire in positive to the switch and run the wires up through the backseat and center console. on is OE behavior, off is just like the golf tee mod, it turns off the valve and leaves it open.
Cost less than $20
If you wan't to make it permanent, just snip the positive wire (leaving the plug connected) and use these
