2020 tundra, looking for 12v source while truck is running and off when not. It is just to turn on a motorola radio, about 2-3 amps at the most. Main power to the radio is wired to battery, just need a good clean power source so the radio will turn on while the truck is running. Even ACC hot will do the trick too. Would like to take it from the fuse box or off a wire with a tap and fused.
