What year is your bike? If you haven't touched the wire harness, it's possible that the connections were last made in Hamamatsu, or wherever their factory is. Get some Deoxit spray and one-by-one, disconnect, spray, and then reconnect several times the connectors. You can use a bit of dielectric grease on the females before connecting the males, when you are ready to make the connection for the last time.
There are cheaper electrical contact sprays, but Deoxit has a good reputation for doing the job. Think of it being like automotive motor oil in your engine vs. motorcycle-specific oils containing the friction modifiers for wet clutches and the gearbox.
FYI, the round barrel connector under the left scoop is the one to unplug when the VBoost cycles to the 'open' position, when you turn-on the ignition, if you want that small-block, cammed V8 sound at idle, for making your presence known at bike night.
