Armor Up! A mod to make armor more better. New PA Utilities pack!

I’ve been trying to do similar mod. But I’m unsure where to start. Especially with having power armor change stats based on whether or not it is activated. Or having other actions occur (such as an active defense shield) when the armor is turned on is really throwing me for a loop. I don’t want to incovience you, but any advice on where to start would great!
