More panel work. Didn't accomplish too much in the way of connecting things, but did a lot of harness work.
Dug out the EIS & EFIS harness goods along wiht the SafeFly GPS & uAvionics Echo UAT ADS-B module.
Assembled DB25 connector shells after ensuring wires connected to the proper pins in the DB25s. Plugged needed wires into the EFIS harness shells as they come unpopulated. Fortunately each wire had a DB25 connector pin already crimped in place.
