Brief Description: Connecting the GMA 240, GTR 20 and GTR 200
Decided it was best to assemble the audio wiring harness as much as possible before placing in the plane, While this is not a bad idea, I later learned that the connectors for the GMA 240 audio panel are different from all else, and the shells must be place on the wires before any pin outs are down.
