...I think John's request is for the actual part models associated with the ports on the back of the instrument. I downloaded the files for the G3X and opened up the STEP file for a unit. Like any sand-filled solid, the entire assembly has been converted to a part and the male and female harness connectors are already connected, sans the wires. I am not an expert at SOLIDWORKS, but I think you could remove the harness connector from the port and look at the Manual to determine what connector is needed. That would take some work. I think John is hoping to convince Garmin to do that work for us so we can download the instrument as a STEP and the connectors with part numbers that we could order from Spruce. Am I right?
