I just bought a boat with a 1990 90 horse mercury, this is the first boat I have had that has a kill switch on the controls. Probably a dumb question, but how do I get the kill switch strap back on where it is suppose to go? I pulled the kill switch strap out, and it looks like there is a little bar where the strap goes back on at, but I don't wanna mess something up, getting the strap back onto the control box.
