Anybody know what this plug could be for?

Found this capped plug around the battery area on my 09 yfz450r. I have had low rpm hesitation on the quad being bone stock since i bought it from original owner and have went through everything to not figure it out yet..working on trying to fix it with my pc5 (new) atm. Any input greatly appreciated!

It looks like it could be the taillight plug, do you have a taillight on it?

Cherry bomb plug. NOT.

I asked same thing and someone said a diagnostic plug.

Not tail light that works fine, always been curious why its there..not sure if it would say in a manual if anyone has one? I would think so if it was a diagnostic plug.

Jesus even worse. Preview looks crystal clear, however soon as you post, garbage. Both attachment and pic upload feature. Sorry guys, I tried. Important thing is, mystery solved itís a diagnostic connection port as most suspected. Straight out of the manual that you canít see in the pics lol
