Count me in with Stomper. Choke is a great backup, but if the needles arent set right, its not an immediate kill.

You plug any standard radio switch into the EDR kill setup, there is a diagram that shows you where and how that comes with it. If you dont have the documentation, I'm sure you can get it on the Electrodynamics website. If that doesnt work, give me a buzz here, and I'll make a copy of mine for you.
