Sentinel Tech
1 & 2. Both are located in plain sight against the two right corners of this room.

4. After destroying the second transformer, another piece appears at the base of the giant Sentinel head.
5. After destroying the third transformer, the last piece appears at the base of the giant Sentinel head.

1. From the first rewiring, head all the way down the pipe.

You don't go "down" any pipe. You continue along the one you stand on to rewire the bulkhead panel, dodging the electric bolts as you go. It's at the top. If anything "up" the pipe that you're standing on. This guide isn't very clearly worded for most of these, such as:
