2012 lx tweeter add

Hi all 2012 lx sedan user here. I got a good deal on the lx even though I wanted the EX it wasn’t available so I had a shop replace the front 2 speakers with the Rockford rx165x3 and I also have a 1770nex installed. I’m wanting to add the OEM tweeter pillars from the EX/EXL (there’s ones on eBay) but how would the wiring work? Since the factory setup is a 4 speaker system I do not want to add an amp/subs just the tweeter pillars if it’s easy. Just curious on if there’s any adapters needed or what they would tap into
