Speed Cell battery install 2016 R1...3rd wire connection?

I bought a lightly used Speed Cell lithium battery earlier this year, intending to install it in my 2016 R1. I did send it in to have it tested and it passed the company's test. While I am aware that I'll have to Dremel my battery try to fit it (I still have the ABS pump in place), I've been wondering where the third wire with the spade terminal goes? I've been told that it fits into the fuse holder?

 

Nothing?

 

extra wires on lithium batteries are usually used for balancing them on chargers made for li batteries. If you dont get any more feedback here Id just call speed cell to confirm.
