Easy is good. I will give that a try because I haven't decided if I want the 12v outlet socket to be dependent on the key being switched on. Hand warmers for sure I want to be off when key switch is off. I might run a fused line directly from the battery for the 12v outlet.
<3amp draw from the grip warmers seems too low to cause problems but if anyone had bad results using the brown and black wires (for any application) please post up or post for what you used them for if you had no problems.
