I chose the phone jack for a couple of reasons. They were readily available when I went looking for parts. I could get all the lights connected with a single plug. And when I saw them, I thought I might be able to mount the board on the fuse and plug on the wing and break off the clip on the plug in such a way that they would connect and disconnect as I placed the wing on. Just one less item to fiddle with when mounting the wing to the plane. I've considered making up a similar setup for servos. I got the idea after seeing air connectors designed to engage and disengage retract air lines when mounting the wing.
