My car: 07 Exige S
I may not be calling these things by the correct name...
I have three gauges. One is a clock and needs constant 12v. The other two are AFR and Boost and require some initialization time and need to be connected to a switched 12v source that STAYS ON while the motor is cranking.
Right now my car is apart and no battery connected, so I can't do that fun wire-hopping exercise with a voltmeter at the moment.
I am hoping someone can tell me the behavior of our switched 12v sources. If I am reading this diagram correctly, can I use my head-unit's 12v power as a safe constant from the battery (is this the equivalent to fuse F15 in the front box??) while using cabin Fuse C2 as a source for the AFR and Boost gauges that need power DURING startup?
Looks like I just need to avoid fuses C1-C2 but I am not sure if I am translating "ignition", "battery", and "start drop out" correctly.
Or do I need to wire my own new fused constant from the POS+ tap in the front?
