Swap the hi lo wires in the thumb warmer.This is a friends sled. Still waiting on my snowcheck. He updated the display and the warmers are there now but can’t be adjusted. Hopefully a future update could allow us to to adjust the preset high and low temperatures. I mainly want to be able to set the thumb warmer higher. I frequently have hot hands but a frozen right thumb on rides.
Then with the switch on low (grip setting) you have the thumb on hi.
