When I got to the point of wiring the ARINC-429 Module, I realized that it needed an addtional serial line from the GNS-430W. This reqiured a little rework of those connectors and the cables that ran up to this connector. Turned out to be an all day affair. But I completed the wiring of this connector and temporarily mounted the module to its mounting, which has yet to be finish rivetted.
