Default Road King combo speedometer/tach install HELP

I can’t believe I’m here asking for help with this, but here I am. I’m trying to install the H-D combo analog speedo/tach on my 2020 Road King Special. I installed one of these on my 2018 Road King and don’t remember having any trouble.

When I plugged it in where the factory speedometer plugs in, it gave me a NO CAL readout on the LCD. A quick look through the instructions says it needs plugged into the 4 way connector on the bike (data port) using the harness that’s included. Okay, fine. But I can’t find that anywhere. I’ve looked under both side covers and under the seat.

I’m pretty sure this was supposed to be a plug and play, as others have indicated on the Facebook groups.

Could the PV tune be causing any issues?? How do I fix this?

Here is the plug and the instructions.

I believe that the data link connector is located behind the left side cover. Should be Light Grey in color with a black rubber plug installed.

There is a connector there but it’s not a four way.

That's why I asked. The data transfer cable had me scratching my head. It was used on older models.

I’ve had similar on my 2021 RK that I’ve traded (don’t remember part no). It was plug and play - just unplug old one, plug in new and that’s it. It transferred data w/o any effort from me and got “married” to the bike after 30 or 40 miles.
oh and mine didn’t come with any transfer cables.

Okay, new problem popped up today. My bike does not have RDRS. The T/C light illuminated in amber on the gauge today while cruising around normally. No codes come back in the diagnostic mode. Suggestions??

The instructions say bikes equipped with RDRS and ABS will require a dealer flash. I have ABS but not RDRS.

You need to take it to the dealer, it needs to be reflashed. I’ve had the same issue on my 21 - once speedo got married to the bike TC light came on.
