ALTO TS112A Black and Red pin connector - where does it go?

I have a pair of Alto TS112A speakers out of warranty and have to replace the input PCB on both - when I removed the back panel I find that one speaker has the thin red and black cables with a JST 2.0 pin connector connected to the INPUT PCB panel and the other to the AMP PCB panel - so I just need confirmation from anyone out there that can tell me which one is correct?
