I found one that was switched with ignition on.
    Murray ... was replying to shawnguess, who was having questions about a battery-based concept for engine bay lighting. Murray seems to be more detailed info early in this thread about the back fuse block.

      OOPs, seem to be too many threads. I got bounced around so much I got dizzy and light headed. Please note the pun.

        Murray ... numerous reference to switched-on power for the engine bay lighting. What about lighting the engine bay when the car is not switched on? Seems there is interest in that. Perhaps a controller that shuts off lighting by a programmable setting? LED lighting is not too power consuming, although a controller might be some drain.

          A quick google search found several 12 volt timers.
          There is likely an unswitched fuse location as well.
          There may even be timers that have an app for your phone.

            Saw “rock” lighting, made for vehicle undercarriage lighting, as candidate solution ... certainly rugged and waterproof. Some have a remote bluetooth remote, some have a smart phone app. They have timers on them. Saw one on a FB C8 Group already implemented. No insight on how it was wired up yet.

              Be simple to make a PCB or even with just a Single pole, double throw switch so that switch one position is LEDS to a non switched 12 volt source and
              the other position to a switched source so LEDs controlled either way

              This way if wanting the LEDs on when car is off set switch to unswitched position and if wanting to go off when car is off then
              used switched position

              Or could use a 3 positron rotary switch where one is no voltage to LEDS as any time

              Clearly then add whatever wanted to a timed, pulsing, etc design

That's usually where the headlight fuses and assorted relays are. Being mid engined that could all change of course. I don't have a C8 so I can't look.
                The owner's manual seems to reference only two fuse blocks, one behind the glove box, and one under the speaker in the waterfall (behind the phone holder). If there is a fusebox in the engine bay, we're not sure where it is.

                  No fuse box in engine bay, the one on bulkhead between seats also support the engine functions
                  Should be easy to do what is needed to get wires through bulkhead where the main wire loom goes from engine bay to that fuse panel
