I recently purchased a 2020 General XP 1000 Deluxe with the Stage 1 factory audio. The machine I ordered (with ride command) was taking too long so I settled for this one. I then bought the OEM Stage 4 kit from Polaris and went to hook it up and found I am missing a harness to plug the amp, subwoofer and rear speakers. Since the $1500 7" display is not that important to me, is there a harness available anywhere that will plug in to the PMX-2 head unit, amp, sub and F/R speakers? Only reason I ask is because the Rockford Fosgate amp has a 23 pin connector and I have know idea what is what.
