changing vanilla ped uniforms to custom eup.

Alright so I'll preface this by saying I have no idea what im doing and i'm new to this stuff, with that being said I've looked at how to change the ultimate backup peds to wear my custom eup outfits, however when I spawned the female code2 backup it used the vanilla uniform, it doesn't with the other female backup that spawn, (as I edited the ped chance so they would pop up once in awhile when i call code2 backup). It seems to specifically only do this with the Female Code2, so I figured that whatever was making them spawn with the vanilla uniform I would just change the vanilla uniform, however after watching several tutorials and downloading the EUPFR and UltimateBackupEUP mods, and trying to edit the xml files for them I can confidently say that I am very confused on how it works, I'm basically trying to copy and paste (not literally) my eup uniforms to the vanilla clothing like I did my UB with the glasses and vests and hats etc. I get that its probably very different but I need all the info I can get, 😬 ❤️
