(frisbee @ Sep. 01 2006,23:35) It can be used just like any other switch . Mine is set up on the starter switch . I have a toggle to turn the switch to the starter or to the NOS . I was going to use the pass switch but was talked out of it because someone said if I ever go with a air shifter I would want to use the horn button and it might be hard to operate both buttons that are on the same hand. But all you have to do is devert the power with a toggle.
