Harry, The electrical connector you need for the heated grips is behind the left hand front side panel. you need to undo the two allen head screws. Then there are four plastic push button poppers to remove, two at the top of the inner fairing and two at the bottom. ( you need to push the little tiny circular on the poppers inwards to release them ).
Next you need to push the fairing forward, to do this I found that if you push on the right of the fairing forcing the fairing to move to the left ie: towards the front of the bike. You need to do this to disengage the two hooks that hold the fairing on. It is very easy and I hope I haven't made the job of removing the panel sound difficult.
You will find an empty electrical plug with two switch lives in it, however I think there is a Honda wiring loom that connects to the plug which you may need unless your prepaired to cut the existing plug off and attach your wires to the cut ends. Good Luck Buddy
