HIhi I need some help me and a good friend of mine found all 4 of the ED-E upgrades but we can't find the last upgrade. Can anybody help us with this quest I love to see what was the last upgrade is like:) The First ED-E Upgrade is in the HopeVille Silo. The Second ED-E Upgrade is in the building by the gas station when you first leave HopeVille Silo. The third ED-E is found in AshTon Silo. The forth ED-E was found in a waste pipe. And that is all we found.We are just missing one.

There's a nuke right of the entry to the Cave of Abaddon or something to that effect, detonate this nuke, and you should see a busted eyebot lying in the rubble after the nuke is destroyed.

Thank you so much. We are going to check it out:)

Where is the waste pipe? I don't know where to find it!

look in the wastewater treatment plant the one by the boxwood hotel. and iam still having a hard time finding the the fifth one.

Those three pages provide minor descriptions of where they are. Looks like the one you're missing has the most detailed description of how to find them on those latter two pages.

Thank you LongKnife we are checking it out:)
