Where does this go?

1975 CB 360t I've fully restored and upgraded by hand. Almost to the end and I can't remember where this goes. Hand sanded every part and rattled can after that. All new bearing/brakes/tires/electrical/hoses/cables...you get the point. Tank and side panels are about to get here from the paint dude and I have no idea where this goes. I'll post a pic as well as a pic I took of the bike earlier. It was a mess when I got it.
Let me know as soon as possible
Thanks
