yes that is important dirt, almost forgot about that. i used to hate the s and s, always wanted the siemens, but once you start using the s and s you will see it is superior as far as installation goes. I have probably installed over 100 s and s starters, and have less then 5 go bad, then ones that have gone bad, unfortunately have gone bad in under a couple of weeks or so. if they make it past a month, they will be in service or many years.
