Does anyone now if the ST models come with a 12VAC+ main power terminal somewhere in the rear/cargo area similar to how the Police Interceptor Utility models have that allows upfitters quick and easy access to 12VAC+ to power up two-way radio packs, warning light systems, etc.... if so, where can I find it in the ST model? Or does the ST model have an alternative 12VAC+ line that can be tapped off somewhere in the rear cargo area that has sufficient amp capacity to support two-way radios, lights, etc.?
