Need 12 volt hot power source...
looking for a 12 volt unswitched power source.
I am going to hook up a CB Radio and I want to be able to turn it on with out the key in the ignition.
Obviously I could run a lead right to the battery but I am looking for a clean power source.

Thanks.

Wouldn't a wire directly to the battery be cleaner than any other source? Then you wouldn't have any static being developed by the alternator, heater fan motor, turn signals or any other electric component.

Chris is right, right next or behind the OBD port, you'll see a wire harness, a plug in of sorts, tap into the hot from there, I want to say red with blue trace but not certain. I ran mine right to the battery, its clean.
