Garmin supplied shield drain termination hardware (8-32 screws, lock washers & plain washers) with the GTR200 installation kit only. The holiday period has slowed delivery of mail but today the hardware I had ordered for the remainder of the connectors arrived and I terminated the drains for the connectors so far completed. I also installed a temporary connector in order to test the GMU11 remote magnetometer, that all works correctly sans not yet being calibrated.
