Continued: Battery Drain

[particlewave]

If it's draining the battery overnight, it has to be a significant drain. I would disconnect the positive lead, then attach wires to both the positive post and the positive clamp. Run the wires outside of the frunk so you can close the lid (having either frunk or trunk open turns both lights on, so removing the frunk bulb is not enough - best to close the lid to eliminate both). Hook up ammeter to the leads, then turn ignition on to wake the car up. Shut ignition back off. Read current draw. Check every hour. Report draw.
