Testing most of the interconnects between the avionics. So far the two 4500s are talking to each other, the 430W, SL-30 and VP-200. Had to RMA the GTX-330 transponder back to Garmin for a suspected internal short.
Nice to get to this step. Still quite a few bits to hook up yet, but making progress. I wanted to get all the wiring done before the top skin gets put on.
