I think the primary issue is whether you have the Honda sub harness or not. If so, then you have one installation path. If not, you have a bunch of different options with varying cost, complexity, and flexibility
I believe with the factory heated grips and 12v plug you likely do have the subharness, but others that have it will have to chime in. If so you can search this forum for several threads on installing auxiliary lights with the harness.
