Help me id this electrical part?

It's in the battery compartment. The wire on the right is disconnected, and there's a disconnected frame ground nearby, but the connectors do not connect as is. The connectors on both the frame ground and the mystery component are female - they're both double connectors, post connector is the correct term, I think.

Also, should disconnecting my taillight and rear signals affect the operation of my front signals?

And lastly, where's a convenient place to tap into switched 12 volt for my dyna pickup? And what does the term "switched" refer to?

Thanks in advance,
purls

switched means its not constantly hot

Some of the bigger kawasaki's have/had provisions for aux electrical power for gloves and vests. They had their own fused power taps.

Assuming this is actually a power tap, and I can get my tester to light, couldn't this be a good choice for my coil voltage tap?

EDIT: mystery part is an accessory fuser. Thanks mfolks.
