How do I make a vehicle spawn with a custom loadout?

I am trying to make a sunburst that spawns with some of my mods (engine, turbo, trans) active by default.

Can anyone how this can be done?

I thought I just had to change the name of the transmission in the .pc file but it's not working.

This is how I have the files set up:
Documents>BeamNG.drive>mods>sunburst_mod.zip>vehicles>sunburst>
This is where I think I have all of the required files:

engine_mod.jbeam
turbo_mod.jbeam
transmission_mod.jbeam
info_mod.json
pic_mod.png
mod_setup.pc

My modded engine, turbo, and transmission do work. The "pic_mod.png" image shows up as an option for a sunburst, but when spawned it has a standard loadout. I can find apply the "mod_setup" afterwards through the game and all of the mods work.

Any help would be greatly appreciated,
Thanks!

 

The filenames don't match up. It should be:
info_configuration.json
configuration.png
configuration.pc

 

That helped, thanks. but now it's not using the engine listed in the .pc file. It's using one from a different mod. any ideas?

SOLVED: I had a loadout with the same name in this folder:
Documents>BeamNG.drive>vehicles>sunburst
