I installed a fuel pump kill switch and a gps tracker . I know it may sound dumb but I plan to install a small can of tear gas placed in a bracket hooked up to a small actuator which will release the gas into the cabin by a tube that will be routed to where the vent is by the map lights. I will use a 2way alarm and some sensors to detect a break in. I know its not legal and can get in trouble but I love my Z
