the pingel is what came on them and will plug right in. i'm not sure with the pro design, i think it will but it'll take some fancy wiring. i believe that when the tether is plugged in the machine won't start and when it's pulled it will. it'll work opposite if wired the conventional way. i could be wrong, so don't go on my word, lets see what others have to say...
don't use a pro design, it is the opposite procedure for closing the system ( rather than opening ) i believe.. and will blow fuses like no tomorrow, everytime it is pulled. Save yourself some money and time and get a pingel from haydug..he's the site sponsor!
I was looking through Dennis Kirk Atv catalog and noticed that there is a company making kill switches similar to the pro design but they are offering them in two versions with open circuit and closed circuit. I will look later and post the name of the company.
Don't do it. I tried it earlier this year, but went through coils like crazy. I was told you could hook it directly to the coil and it would work, but it's not worth it jut buy the pingel and save yourself trouble.
don't even need ends, they are already there, unplug i think the brown and black wires, plug in the red and blue ones..simple as that ..don't quote me on the colors though ( they are labeled as STOP)
