just had an idea. for those that dont have AC and live in a ungodly hot area (like me) and do not want the startup/shutdown controller trying to come on untill the cabin of the car is at an acceptable operating temp, use a tempurature controlled switch. it would need to be variable to be able to come on at a specified temp. the only thing that i can think of is a fan temp switch for a cooling system. but in order to have one that comes on at a variable specified temp, you would need to use a VSC(variable speed controller). i hade one of those on my electric fan conversion on my blazer.

just an idea. i have not researched into temp switches for suitable for such an application.
