Trying to Add Zero's Job Finding Feature to a Career

Hello all!

I decided that, given how Zero has a working example of a successfully customized career package and a video tutorial for how to do this included in their patreon for the Job Finding mod, this would be an easy first mod to start with.

I was wrong.

I'm trying to modify Katato's Ultimate Nursing Career, purely for personal use. But I'm running into snags because I'm having difficulty parsing what files come first. For example, using Zero's tutorial, I can tell that one of the icons I'm supposed to replace comes from a Career Track Tuning entry with an <n = "icon"> tag. But I can't tell which one; presumably it should be the entry level one, so not one with a <salary>10</salary> tag either, but that still leaves about five options to pick from. Is there any way for me to see what each tag is pointing to if it's not included in the .package? Like, how would I figure out what the value of 

<T n="career_description">0xB5173A47</T> is?

EDIT: I did check the tutorial index, but I couldn't find anything related to jobs, though I'm not sure if I'm just not looking in the right places
