I've loaded the model in Blender. You need to check out Normals as half of yours are inside out.

See this youtube for an explanation https://www.youtube.com/watch?v=46fIGJ75z-k&ab_channel=CGCookie

Check if there is actually UV information in the Zinyak model.

So i added a texture to a cube and it loaded. Then loaded the same exact texture on zinyak but it did not load in blender

You succeeded to bring it into TTS, that is already one achievement, so well done on that.
I recommend you open it in Blender and do some operations like recalculate normals to outside, triangulate all faces. This should fix the issues with the model looking broken up and weird.
If the model has a UV map and textures as well, then take a look at this guide I made, it is for a now older version of blender but the same principles still apply.

Section 2.3.1.

This was my first time adding a mod in tts. And used sr4 model viewer to export it. Any other way i can export a cc_mesh? With textures.

Sadly there is a lot wrong with this model. If you have any questions, I can help.
