Rear blinkers are 2-wire... fronts are 3...
You can use 2-wire on the front but you lose the running lights...
Heated grips will probably drain your battery eventually...
They do make battery operated heated gloves, or you could use disposable or reusable heat packs in your gloves...
Without the front running lights, and using low beam headlight,... you might have 20 watts or so to play with...
Heated grips can pull from 10 watts up to about 40... some have adjustable settings...
I doubt you feel much warmth from 10 watts...
...
It's an iffy proposition on this bike... it just ain't made for electric accessories...
