I'm trying to add a custom gauge texture to a mod of mine, but I can't figure out how to do it. Can anyone teach me how to? (image attached as an example - Rubie's SILLY-15 MEI mod)

You add a texture page to the main object (not a subobject).

Click in the "type" column where it says "fixed" and select "dashboard backing"

Now you should see that texture on your dashboard when you visit the dashboard editor in vehicle editor "Textures" section.

Quote from Flame CZE :

1. Save the backing texture as a square PNG file in data/png.
   
2. Open the Modeller.
   
3. In "subob" mode, make sure you have the main object selected.
   
4. Go to the page mode by clicking the page button or pressing 7.
   
5. Click add new page and load the backing texture.
   
6. Click the fixed button to mark it as "dash".
   

Thank you!
