Picture your RJ11 plug from the top. Lable the slots in your mind.
|3|4|5|6| We only use 3,4,5,6 becouse we are using 4 positions. If we were using 8 positions then we would have the full 1|2|3|4|5|6|7|8
Pin 3 will be the white orange, pin 4 will be the blue white pin 5 will be the white blue, pin 6 will be the orange white. Then to your 66 block you will lay them down in order white blue, blue white, white orange, orange white. Once you cross connect the pairs to yor station cable it is key that your jack is cabled out with pairs 4,5 and 3,6 being the same as what you crimped.
Hope this helps!
God Bless
