Gentlemen, based on those emphatic responses - PC8 it is.
Last question - if I get the relay that has the switch function - which switch did you folks buy and where did you install it? I looked at the Eastern Beaver site and was going to go with the red switch that comes with the black housing and mounts on the handlebars. I'm assuming the R3 bars are 7/8" or 1" as per the switch specs. This switch wouldn't really fit snug with the grips on the R3. Does it look awkward at all kind of floating on the handlebars? Thanks!
