Depending on the manufacturers technique and preferances, some decided to send 12V power to the accessories including the instrument panel through the ignition switch. I dislike that because ignition switches don't generally like to carry heavy accessory loads. Others ran a separate 12 or 10 gauge wire pair (positive and negative) directly from the battery to the helm with a 30A fuse in the positive lead within a foot or so of the battery. The ignition switch then got it's power via the harness running from the engine bay or outboard. Since there are two 12V sources in your case, I suspect you have both connected to the switch. If that's the case, the red wire and a ground should come directly from the battery and connect at a 12V and ground bus at or near the console. The orange wire is likely the 12 volt feed from the engine harness. Only you can sort this out especially if the wiring has been messed with. You would NOT have two 12V sources feeding the same accessories.
