Update: Harness 12689504 will be a direct swap for harnesses for anyone with a 2019 trying to upgrade the hpfp to the lt4 pump.
Original:
Everyone that’s done the lt4 hpfp upgrade where the connectors the same. My connectors don’t match up. Lt4 pump 12694529 and my old pumps numbers 12697967. First pics new pump second is old.

Anyone have any idea thought these are plug and play.
