The decision was made to change the overhead panel from automotive circuit breakers to aviaiton type. Several circuits were being added such as radios, lights, heater and and the original wiring scheme had some issues so it was decidied to start from scratch. I also added some LED eyeball lights on the panel and some dimmer switches.
My brother, Mike, was invaluable in helping me with this. His experience with VORTAC and ILS maintenance allowed him to look at the big picture while I was the worker bee!
