  I don't have this setup but was interested in how the heater worked so I found the attached from BattleBorn. Maybe that will help as it looks similar to yours.
  
   Inside the manual it says:
  
  Step Three:  Deactivating the Heat-Enable Function To deactivate the heat-enable function on your heated Battle Born Battery, simply remove the heat-enable jumper wire from the heat-enable post. Remember to tape down the end of heat-enable jumper wire with electrical tape and cover the ring terminal so it does not make contact with other live wires or grounds. Be sure to put the heat-enable screw back into the post so you don’t lose it.

  Yes. I think one of the wires on the positive post goes to the switch so you can remove that one too.

  Hi,
  
    I also removed it my 360, when I upgraded my battery.  I used that  wire and circuit  for  a new 12V plug toward the rear (where there is not one).  The battery heater wire in our 360 went to a dedicated fuse in the WFCO.
  
  What are you doing with your 100 aH battery..I've been trying to sell mine for $450 for a while but no bites.  Trying to figure what i might use it for.

  The wire is connected to a toggle switch to enable or disable the battery heat.
  
  My 2024 320S uses a lit toggle switch, as I show on my DC wiring schematic, bottom right:

  If your SOK doesn't need it, it'll be an unused switch I guess.

  Thank you all for comments.  Question answered.

  Yoshi asked: “ What are you doing with your 100 aH battery..”
  Well, I was going to try and sell it, same as you.  See how it goes I guess.
