Ignition wiring question

[TerryA]

I'm midway through replacing my fuse panel. The original was ok until part fell off so it's replacement/update time. The old panel had labels for instruments, lights etc as expected but also for the bilge blowers which surprised me. The blowers are turned on by the ignition switch so I assumed they would be powered from the starter battery with in-line fuses and not from the domestic batteries .
The engine installation is "bespoke" (or possibly random) with a Mitsubishi engine and what seems to be an industrial control panel so the wiring is probably also bespoke. Being a wiring newbie I'm wondering if it matters or if I should do some rejigging?

If it was OK for you before, why change it?

All ne to me so I was just wondering. I know it worked but that doesn't mean that it's a good idea.

Just because something works, doesn't mean it's wired correctly or that there isn't a better way of doing things, so you are right to question it.

If it was me, i would wire the blowers to the ignition switch, fused close to the switch. In order for them to be on, the ignition would need to be on and the switch on too.
