Hi all, putting an OEM radio system in my wife's '15 base model. I have the harness in and connected, with three exceptions. I've searched the past thread, but can't find a definitive answer for what the below three connectors are for. Can anyone tell me what these connectors are for/where they go? Thank you in advance!

PS: The radio powers up without any of these three connectors plugged in, but none of the buttons on the interface work, and the speakers are barely putting out any sound.

I installed a round marine radio in my 2015 Base Slingshot, so I didn't use the factory radio harness, just an aftermarket connector to connect the radio power connector from inside the radio cubby area to my aftermarket radio. I don't know about the OEM sound system, but this Parts Diagram may be helpful - 2015 Polaris SLINGSHOT ALL OPTIONS (T15AAS/AAP) Electrical, Sound System T15aap All Options (49Slingshotsound14sling) | Cheap Cycle Parts.
