It's hard for me to understand from your post, but for me I plugged my LED strips right into the node pro, or into an extension that goes into the node pro.
The lighting node pro uses LED strips with 3 pins - 5V, Digital Input, and Ground. There are 2 possibilities for your 4 pin strips:
1 - They only actually use 3 pins, 5V, Digital, and Ground, as in the left of this picture:

2 - They use 4 pins, 12V, Green, Red, and Blue (in the right of the picture above). If this is the case your probably won't be able to use your strips with the LNPro.
