Another question for this group (if I may ...) In my previous photo, you can see the backside of a 12V cutoff switch. And also a mess of wiring related to the Holley Terminator-X I have mounted in the roof of the PS foot box. I am considering providing 12V power for the EFI control via the switched side of the 12V cutoff switch. This seems logical as this would assure cutoff to power for the fuel pump, which in an "emergency", is maybe the most important function a cutoff might provide.

However, if one is using a cutoff key as part of an anti-theft scheme, such an approach I think means that the Term-X might go through a re-learn process. Am I close? There are a few other threads I have spotted that discuss Terminator-X parasitic losses. I have not measured / do not know if this is a valid concern? Can the cutoff help in maintaining the battery?

Thanx for any insights !!
