Where does this plug go?

Hi,

I'm slowly putting the Hobby back together. I have two plugs behind the dash near the speedo which I can't see where they go? Do you know what they should plug into? I can't see anything left over that hasn't been plugged into, unless I'm missing a switch somewhere? I can't find the air vent from that side so I may have a switch in a bag I need to find!

Thanks,

Daniel
