   Where to take switched 12v power that doesn't cut out when cranking?

   I originally used the efi relay control side voltage but it cuts off when cranking. I figured that over anything else would stay energized during cranking but apparently not… problem is that the ecu shuts off and can’t start the engine.

   Where to take switched 12v power that doesn't cut out when cranking?

   As the title says, I need 12v that turns off when the truck is off, but stays on during cranking to run my ecu for my turbo. Anyone know where I should try? Currently I am using the BATT pin off the ecu harness but it stays powered on at all times even with the truck turned off. Thanks!
