Replacing an image Texture within a node Group

Hey everyone,

I’m currently stuck with a problem.
I have a node group with a texture in it. Now I want to replace the texture node with something like a placeholder which gets 1. The Image Texture from outside the node group and now the difficuilt part 2. A Vector input which is coming from within the node group but effects the image texture which is coming from outside.

I hope y’all get what I’m trying to do here, thanks in advance for your help.

I actually tried something like the quick example below, where I used a checker node as a palceholder. It kinda works, but the vextor doesn’t actually effect the Image Texture.
