Help converting a Custom Race to SAM (LE)

[goodisyo 0]

So i've been trying to make Carlos in this mod pack compatible for SAM on skyrim LE

SC - Jill & Carlos | Annie Lenine on Patreon

i followed two guides i found using Tes5edit and creation kit, i followed instructions as much as i could but no matter what i did they kept coming out wrong, there's also underwear on the model and even when i try to get rid of it it's still there

i was hoping if someone would be able to edit it for me? i'm completely new to this sort of thing and i've tried for hours to the point i'm defeated over it ;-;
i just want Carlos with a "member" that can work with SAM so to speak

any help will be huuuuugely appreciated
