Bench testing convertible top motor

[Merc Cruzer]

Could anyone help me with bench testing a 4 wire convertible top motor for my 1953 Mercury Convertible. I have attached a few pictures to identify the wires, hopefully the colors of the wires are distinguishable. I want to figure which combination of wires to attache to the 6 volt battery without the use of the relay. The color of the wires: the two on the left are white or possibly yellow, the second from the right appears to be black and white and the one on the right is green.

Thank you for you assistance.
