Kma 130r can’t connect hip battery back

[Jermedic]

New kma130r and the plug on my hip pack AP battery pack looks different than the kma130r connector

they almost fit ...

One has four pins in a circle

the other has four pins in a circle and a couple spade terminals in the middle

I know absolutely nothing about the electrical Stihl stuff,
but looking at the kma130 and the kma135 repair manuals, only the kma135 discusses the remote battery option. Maybe that is why it won't fit the kma130.
