Proportioning valve help needed

Working on my 66 dart and I am changing the brake system to use an 11 3/4 disc brake setup (cordoba set up) along with drum brakes (10") on the rear. When I bought the front brake system/parts I was given this proportioning valve to use in the change over.

Was wondering if anyone could help me with a diagram of how this should be piped up. I am using a master cylinder that I bought from doc diff that is a dual cylinder. It appears all lines going into this valve are 3/16".

Thanks in advance for the help.
