Shield Generator Help...

Howdy,
I am having a go at creating a replacement for the ORP mod since its discontinued and needed help finding a few things…
I cant seem to find the engram file for the Tek Shield Generator anywhere. Every other Tek item seems to have one except this one.
Also How would I go about editing the properties of what it does in the dev kit? I have created my own folder in the mods folder and copied over some of the needed files but I dont see anywhere to change specific functions such as what selections you get when you walk up to the object and hit use key etc…

Any guidance would be appreciated. Thanks!
