Identify electrical connector, (‘07)

Dear friends,

Can you, please, help me identify #1 and #2 on the photo? This is half electric, half ... unclear.

I took off the fairings to clean out spider webs and no matter what angle I tried looking from, no matter how much I swore at it at different distances and various volumes [ after attempting to court it, at first, of course, with candle lit dinners - as per manual ], I can't figure out where #1 goes! I've even printed out the diagram [ ] and asked it to point to the location. However, after taking several shots of vodka, I am still unable to identify what it is.

The wires going to #1 are Yellow with Black Stripe and Black with White Stripe.

#2 was a total surprise - I haven't checked if it's a vacuum line or something else. Why would a previous owner [ presumably ] shove a bolt into it and throw tape on top, for good measure? How much extra horsepower does this approach potentially generate?

#1 is the connector to the flapper solenoid. #2 is a vacuum line that used to drive the flapper system. It connects to the throttle body, and people either plug up the hose or remove the hose and plug up the nipple on the throttle body.

For noise control, the air intake has this plastic flapper that closes at low RPM and opens at high RPM/load. Disabling it is supposed to help the motor "breathe" better at low RPM's.

Thank you so much for responding to my non-sense. Honestly, I was kidding about # 2's [ assumption of higher HP ] however, my brief research, does have some legitimacy [ much to my surprise ].

Is it an issue that the "flapper" unit is missing altogether?

What I am asking is ... Is it FINE to have # 1 connector not connect to anything or will it result in some long-term damage?

So, both can be unplugged. Correct? I seem to be missing the actual unit that the wire + hose plugged into. Granted, I have NOT experienced issues short-term [ having under 20,000 miles ] - but I just wanted to double-check. @09_Blade - again, thank you so much for sharing wisdom on the subject.
Correct. To avoid a vacuum leak, you have to make sure the rubber hose is not left open. If you have time, you can trace the hose back to the throttle body, unplug it, and seal up the nipple with a vacuum cap. Otherwise, the bike will run fine as-is.
