It's amusing to see that we all come up with just about the same approach to doing #8. I used the same setup but lowered one piece at a time attaching the next while holding the first etc. Once loosened I just reversed the operation. When inserting the new plug I tape it to the socket and lower it in attaching the extensions one at a time while lowering it in.
After a while you develop a muscle memory and can do it by feel and can keep your eyes shut.
