I just ordered Sportech 45 degree hooks for my '05 RX1. Looking at reviews I see some have cut the grip heater wire installing these. Many years ago I put them on a Vector and don't remember having a problem. I realize you need to be careful enlarging the hole at the end of the grip. I think I used an exact knife before. Tech guy at Dennis Kirk thought I might have to remove the grip by drilling out the rivets holding the grip to see where the wires are. My dealer told me as long as I go straight in from end of grip and don't cut the end of the grip off I should be fine because the wires don't quite go all the way to the end. Has anyone out there installed these? Thanks for any reply!
