I recently acquired an avionic pull that included a Crossbow 425EX and a Crossbow CRM500GA magnetometer. These were from the same installation, but did not include the wiring harness. I have not been able to find any documentation on interfacing the two (Tim at CheltonEFISPilots.com has no idea). Anyone flying this combination? Would you be able to provide at minimum a pinout diagram for the AHRS-magnetometer interface? Any help would be appreciated.
