What kind of accessories are you trying to power with the ignition off? Some people have experienced no-start situations just from running high powered stereo systems while waiting in the car while the wife shops. The outlets could be made powered without the ignition key but one risks the danger of excessive battery drain resulting in a no-start situation and/or damage to the battery. On my jeep I installed a power distribution relay box with multi-switch pod that can provide reliable 12V power for accessory lights, air pumps, etc. It has an Integrated LVCO (Low-Voltage-Cut-Off) circuit that detects the battery voltage. Doubt if you need such a system but they are available.i need to know if any of the 12vdc outlets in my 2012 are live with the ignition off or is there a way to make one live?
