I have a pair of Widder Gloves and the wiring harness that came with them is a series type circuit. After purchasing the Gerbing Jacket Liner pre-wired for gloves, and some extensions. I decided to try the Widder Gloves using the Gerbing pre-wired hook-up.
I cut the un-needed end from the extensions and connected a Widder type end to the extensions, so that each glove would connect to each sleeve connection. I can still use the Widder gloves with the original series connector if necessary.
The Gerbing Controller is a pulse type controller. When I turn on the gloves, I only turn the control to approx 1/4, as soon as they are warm enough, I turn them back to just past the on "click". and they keep my hands toasty. Down below 30 deg F, I have to increase just a little. I think you could probably turn it up enough to burn out the wiring in the gloves, because they will get really, really hot at half way. TOO HOT!!!
Hope this helps.

I like my Widder gloves but they are not Watterproof, just water resistant.
I have sprayed them with campdry, but it doesn't help much.
