Random plug-in under dash in my Rzr 800

I just noticed this random plug in under the dash of my Rzr 800 it has a added 9v battery plug In and a 3 prong plug in. I just wanted to see if anyone knew what it is for. I just assumed it was for a fuel controller but figured I’d just ask. Thanks in advance for any responses.
