I made labels for the master contactor - both ends and got those installed on the aft end, then crimped on a connector and attached it to the post of the battery contactor. I also put the battery tray back in position, but I know I will have to remove it to put the pitch servo in place. I checked continuity on the master switch wire, and it is good, although I will need to recheck it once the switch side connector is crimped on. I also ran the ground wire for the starter engaged light. Making progress.
