Bought this Boom Stage II off of someone, came with this extra harness. After Googling, all I could find is that it's an "interconnect" or something.

'16 Street Glide FLHX, just fairing speakers and amp. I did however run the harness for lid speakers just incase I upgrade...

Any ideas...?

 

It is a harness for the rear speaker interconnects

 

Okay so I don't necessarily need it hooked up now since I just have the fairing speakers
