Roll the ribbon cable around a non-conductive form 1/2 inch in length, such as a small plastic tube or a piece of small diameter nylon rope, etc...
Put a dab of silicone caulk or hot glue in there to hold it together like a jelly roll.
Place an electrical tie-wrap around the roll.
The tie wrap should prevent the cable from passing through the grommet/case and pulling the connector off the header pins.
Maybe the form is overkill -- but just mashing the ribbon in a tie wrap seems like a recipe for a broken conductor.

Fred tells me the following in an email "The LCD has a particular startup sequence and this will only be done at the T2 startup."
Whereas, I took the WIKI quite literally "No configuration is necessary. The standard Tracker2 firmware will begin using the display automatically. "
So, I just plugged it in, hot. What a newbie mistake!
