LC-1 Wideband Wiring Problem 12V Source

[Flghtmstr1]

I didn't explain myself correctly. You should use the battery for the 12v source, with a relay tapped into an "ignition-on" circuit such as the fuel or ignition systems. Obviously, you wouldn't want to run the power off those circuits, but a relay is the "correct" way to do it. Alternatively, you can just tap it directly into another source like your radio or one of your column wires.

Any ideas on where to route the wires into the cabin?

Drill a hole in the firewall, put a grommet in and run the wires. Just be careful where u drill.....
