What is the plug for that is by the right side passenger footpeg? It's coming out from behind the removable panel. For some reason I can't upload a picture.

 

Is it the battery tender connection?

 

No sir, that is on the left side. The plug in looking at is not an SAE connector, it looks like any other plug on the harness. It has a cap on it.

 

 

strange, I know for the 2017s/M8 touring they make an exhaust fan that goes in that location now. possibly power/control for that fan?

 

here you go, looks like figure 1

That's your dirty bike sensor.

 

Yeah, for the cool flow fan. If ya get one...be carefull how you plug it into the ABS speed sensor...you can roach the rear wheel ABS sensor if connected incorrectly.
Ask me how I know, LOL

 

you have to let us know how that works once it gets HOT out

 

Yeah... I live on a dirt road. Damn sensor goes off all the time! It only stays clean for the few hours it sits after I wash it... And I ride rain or shine, every day. Put 800 miles on it this past week.
