I don't easily see a plug like the one in my picture either. Maybe post this and your picture over in the M8 section for review.

 

Found it. Guess I’ve got a pv for sale.

 

Ahhh, see.

 

its behind all those connectors mine was hidden too look behind all those connectors its there.

 

I Was going to say I watched a few youtube video's and they did say they were changing it for 2021.

Will be interesting to see if they gave you enough slack on your cables for the 5.5" risers I'm going to need a turn signal extension as it's borderline.

 

This is just for the tuning calibration meaning maps only that the sc has available on the device you buy but with your pv it should be different

 

I confirmed I have the new port found in pics in this thread: 2021 FLH/FLT hardware updates & changes

 

I just purchase a beautiful 2021 low rider s
runs great however when I twist the throttle on/of quickly it makes a knocking sound from engine only when I do that when riding everything is perfect I'm a little concern it's my first harley-davidson is anyone noticed the same knockin sound or is it this normal I have 2 year warranty thank you all

 

Hey I would bring it in for a check. My 2021 didn't have the clutch nut tightened, and it backed off and damaged the derby cover and a few things in the primary case. Had 15 miles on it at that point.

 

These engines don't respond instantaneously to very twitchy throttle input, so it is probably your technique. Got to your Harley dealer and demonstrate what you described here and they can set you straight.
