Well, the thing didn't work. Pulled the plug too and still nothing Maybe a bad switch. I'm taking it back and trying a pro armor, maybe that one will work. Thanks again for the help.Disconnect (or cut) one wire (either one) going to the handlebar kill switch and wire your new switch in. Let's say you cut the black wire - wire one wire of your new kill switch to one end of the cut wire and then the other wire of your new kill switch to the other end of the cut wire. Then test - if it won't start, pull the tether plug - if it starts with the tether plug pulled, then you have a normally open tether kill switch and need to exchange it for a normally closed one.
