2005 RX1 Electrical Question

[Deeks]

I was changing the oil on my friend's RX1 and when I took the battery out, I noticed a diconnected set of wires. The female end was marked with a blue dot and I never disconnected it to begin with....at least not on purpose.
Does anyone know what this plug is? I was thinking since it was grounded to the negative battery lead, it could have been a 12v accessory plug that could be used?? Any help would be great!

bueller?....anyone?

It's probably the added on female end for the battery charger to plug into....

I thought about that too but why would there be a male as well? Thanks for the response!
