I don't mean to hijack the thread... but you seem experienced with electrics... so may I ask a question (I own none)?
Jim,
One set is a Widder and the other brand is Gerbings. Now as how to store everything, yes treat your garments with white gloves. Don't roll anything in a tight ball including the harness.
As for the harness to the bike, that I where I only have had a problem. A broken wire going into the on/off switch. That is what I used and actually came with my first vest. Now I have the true Widder control and a Gerbings duel control.
As for heat, both are equal.
The wife has a jacket and gloves that are made in Canada, by a local company that works just great too. She does not use a controller, just fused (10a) straight wiring into the bike. She likes to be warm on the bike.
I also have a digital voltage guage to point out to me when I'm over taxing my small charging system. So far so good as I have never needed a boost yet.
