What year/model bike? Does the exhaust have 02 sensors?

 

If you have a HD manual for the bike in the wiring diagram section it lists all the connectors, the number of the connector and where they are.

 

Welcome Chad. Keeping you on top. WV transplant myself. Only as as suggestion, make you next new post over in the new member welcome area to say hello.

Hope you continue to enjoy your ride here with us on the HDFORUM.

Only as a suggestion, but very important, create a signature line similar to mine on your bike with year, model, and all the letters Harley assigned to the bike. It will appear at bottom of your post.

You can also add a favorite picture to the signature line.

Doing this will be helpful if you ask a question or to someone asking a question. All Harleys aren't the same with many changes and variations over the years.

You can also add a favorite picture for an Aviator postage stamp you see at the top left of your post.

 

Pretty sure that is the connector for the "cool flow fan" Harley sells.

 

Kinda looks like the plug on a rear o2 sensor? If so it should be plugged in under the side cover.

 

Its not for O2 sensor. There are two btw, one black and one gray, front and rear.

2022 FLHX by the way.

I think it has to be the optional third O2 sensor, bank 1 sensor 2. The service manual shows it’s location as under the right side cover. On mine it’s clipped to the brake line and one of the wire colors is off. Sure looks black/red on my bike and manual says black/orange. i didn’t notice it didn’t have anything plugged into it until I removed the exhaust. And since the plug is open without a rubber stopper I was a little concerned. There’s definitely not an O2 sensor on the crossover pipe, so I guess I’ll just seal it up and maybe tie it up under the side cover.

 

Edited: thought it’s #3 but looking closer it could be #4.
