Look in the sch, if neither of the lamp's terminals is grounded (chassis) - then this is that spare terminal on the socket.
If it is grounded, take a meter, and in the female socket (where you plug that one) measure if the counterparts go where the sch says they should. Although logically there are no other option for this wire to go anywhere else other than to this free terminal.
