Hey Jerry,
Thanks for the feedback.
Maybe you could help me with some confusion. You are correct when you state that Harley heated grips will work on 2011 Softails but here's what it says on the online description of the grip I was looking at; "Fits '96-later VRSC™, XL, XR, Dyna®, Softail® (except FLSTSE2/3) and '96-'07 Touring models.'12 Dyna® and '11 Softail® models require separate purchase of Electrical Connection Kit P/N 72673-11. Not compatible with internally wired handlebars. "
Maybe it's the internal wiring that is the issue.
BTW I had Harley heated grips on my VROD for 5 years and no problems. That said, the Heat Demons seem to make the most sense.
