lans: 1. Hook up the wiring for the instrument panel. Status: Started. I decided to begin hooking up the instruments. After determining a location for the Battery and Avionics Buses the next step was to route the wires into the area. Of course most of the wires are stubs from the instruments so additional length needed to be added using splices. I would have preferred not to splice the wires for reliability reasons but it could not be avoided. I also labeled the wires to make connecting and troubleshooting easier.
