This is a side quest attached to the main quest called Get Augmented. Once you start it you will also get the side quest in your journal called Stop the TruBody gang. Talk to Dr.Niles about getting a Neuroweave, he will reveal that he doesn't have one.
Go to Fixer's Hope to the Drug Store and talk to Holm. He will give you more info on the quest and the location of where the shipment is.(The Docks)
Return to inform Niles so that you can accept a tracer to put on one of the packages. You need to do this otherwise you can't find the hideout of the TruBody gang.
Go to the Docks, the first Door is warehouse 21 and is unlocked, if you go to the top you can go right into a door that leads to warehouse 22 which is where your Neuroweave is along with the crate you need to attach the tracer to.
If you have lock picking leveled up to 2, you can just lock pick the door to warehouse 22 and avoid dealing with the guards in warehouse 21 along with a turret. There is only 1 guard on the bottom floor of warehouse 22. The tracer goes on one of the boxes in there, it will highlight it when you're standing next to it. Your Neuroweave is in a box on the right side of the room on top of some other boxes.
Return to Niles after doing this, ask about the tracer and he will reveal that the TruBody gang hideout is in Taijo district. It's all the way to the right of that map, it doesn't show up there until you've done all of that quest first.

Note: Do not forget to do the tracer part, once you get the Neuroweave quest done there is no way to finish the TruBody Gang quest so make sure you talk to Holm and then Niles and specifically the dialog about getting the tracer otherwise you will have to do it on a new game.

Note: The achievement will unlock once you leave the Hideout.
