Figured I'd share this info for anyone running a Terminator X with a cable throttle body. I bought this connector and 26 little blank plugs to keep the elements out of the computer. You can get them at Mouser, but the cheapest I found was Newark $18 shipped to the house in three days. Part numbers are:
1473416-1 (you need 1).
4-1437284-3 (you need 26).
