Spare Connector Under Tank

I want to connect my GPS using the spare connector under the tank and have a couple of questions :-

Where can I get an appropriate connector to plug into it?
Is it a switched live?

thanks

 

It's the left hand one in this pic.
Can't see it in the pic really, but it's a T shaped connector.



I can check it but need to pop the tank off, from what I've found it looks like it's a permanent live.
I'll probably use it anyway rather than add a couple more connectors onthe battery posts.....
