I want to be able to coast with the engine off but leave the ECU, dash, & scangauge on.

From my searching it looks like what I need to do is make a kill switch for my fuel injectors. I went digging through my low voltage scrap wire box and found a 12v 40A relay that came off a HID kit. It is designed as a normally open circuit but I think I can make that work bu using a normally closed momentary switch.

My issue is finding the Injector fuse, any idea as to which one that might be on a 2006 Matrix?

All I saw in the fuse box that might be it was a 20A EFI fuse and a corresponding EFI relay. No hint as to what EFI stands for.

Ideas?
Hints?
