Nytro roll over tether not working

Just got a nytro mtx with the Yamaha factory roll over tether and when I pull the tether plug out while the sled is running nothing happens. I looked at the wiring and it appears to be all correct. Would it be the switch itself that is not working? Is the kill switch normally open or closed? If it is just the switch itself would I be able to just get a new tether plug and change it out? I believe that the switch itself would have to work for the roll over valve to engage but correct me if I am wrong. Here is a link to the valve that I have.

Any help would be greatly appreciated.
