Constant 12 volt

Hi - Was wondering if anyone can tell me what fuse I can tap for a constant 12v power? Long story short, I am putting in a new head unit and my existing constant for the radio is not available. Short of putting a wire through the firewall, any ideas? I have looked at the electrical chart for the LR3 and the only two I see are the amp (which will be used with the new amp) and the head unit (which isn't available).

Thoughts appreciated.
Thanks.

Thanks. I will check the light. My only question - the light goes out after a preset time. I assume this is controlled at the light not anywhere else Along the circuit. ?

Also - original circuit is not available because the actual prong holding the fuse pushed back into the junction box.

If you require an ignition supply, use the green wire on the cigar lighter/power socket
