Makes sense. I think I eventually realized the two heat settings would be controlled by more or less resistance.

I don't know what the wattage is, these are factory grips purchased on ebay.

But, I am giving up. With your help I learned how to wire this up properly, got the system working, but felt only a trickle of heat at the grips. Turned out to be a big waste of time and money as far as keeping the hands warm.

Next step might be to try Oxfords or heated gloves. Oh well.

thanks for your patience and expert advice. You don't learn if you don't try...

Just to close this out – It Worked! yes, it took me a long time and some frustration, but as they say, if you know what you're doing it easy. I started out definitely not knowing, now I do.

Long story short: the power comes straight off the battery to a relay. The relay is activated by simple switch at the bars. The application (heated grips) are powered from the relay. The relay and fuse tuck in neatly in the headlight bucket.

The green/black is a fused line.
I added a fuse in between the connector board and the relay, just in case.

I think it's a pretty cool system and the alternator seems up to the task (it's fresh but just original output). On a simple test startup (crazy salt and ice around here) at least in the driveway the alternator read fine. I'll check more carefully soon.

So thanks again for the great advice.
Can't wait for drier, less salty roads.
