I'd like to add an auxiliary power socket to the cockpit of 707, but I'd like to keep it hidden or make it removable. Ideally, I'd like to fab up a bracket that will hold a two-port power socket across the lower dash support bars, which can be clamped in place and removed with a wingnut. That would mean a permanently mounted (dis)connector somewhere under the lip of the dash.

What have others done for cockpit power in ERAs? Where's the best point to tap +12V with a fused line?
