We're mixing up cable types here.  The green type cable is for Drive CLiQ with power supply (encoders, etc).  The OP is going from CU to MM, which does not need the power supply (the light brown cable).

CAT 6 cable and connectors should work, but not as a permanent installation.  Get the right cable.

Edit:  Sorry Marko, I did not fully read the second half of your post.  You answered the question already.

 Dear casajr,

I am going to use cat 6 cable and RJ45 as connector to connect CU to Motor module. I really need to know the pin layout and color code of the two end of the cable(means which color core of the cables are to be connected to RJ45 connector's port)

But, if you need only to connect CU and motor module, then yes, a good ethernet cable will do the job. Still, you have to find out if it is straight or cross-over.

 Did you find out ?
