Belly of the Beast

Deactivating the emitters in the Kartabula, I have been stuck for 3 weeks. Is there a trick of some kind of trick I’m missing?

Is that the one where you have to stealth your way through three sections of the T’kon ship? As far as I can remember, you get a cut scene to lead you into the next area after you’ve placed the thingy Portal gives you onto their computer consoles. Then at the end, you examine some console and Portal brings a shuttle over to your group.

This is the one. There are 3 to do and I always get killed trying to do number 3. Stumped on how to move on.
