Assembled all of the Garmin connectors and backshell with the GEA 24 to ensure orientation and fit. The brown wires are the engine sensor wires for the EGT and CHT probes - 4 each, two internal wires each. The white wires are the shielded 2 or 3 wires for the other FWF sensors - fuel pressure, oil pressure, oil temp, fuel flow, and manifold pressure.
I have to say that Garmin provides awesome documentation on how to assemble the backshell and perform the wiring. Everything you need to know is in the G2X Installation Manual, a PDF from Garmin.
So far this part of the project has been fairly straight forward.
