ACC Power Supply
I'm having trouble with the power supply for my AVIC HU and I need to rewire the hot lead
I've already used the #22 fuse for my heated seats. Someone posted another supply (a yellow wire) down next to the passenger footwell fuse box. I've looked and I have 2 spare connectors down there but neither has a yellow wire.
Any suggestions for another ACC supply which is only hot when the ignition is on?

you could always use fuse #22 to control a relay and then tap 12v constant from the battery. this would turn that constant 12v into a switching (acc) lead that can handle the load of the heated seats and the radio
