I Must Admit I was a Bit Surprised the first time Viewed the Electrical Panel
Fuses / Relays and all the Plugins / Upon Flipping the Panel over and seeing the Mass of wires twisting every which way I had to Laugh a bit .
Having owned a Ton of Cars this was a " Experience " to use a word .
once I get the Air up and running I do like the Idea of the Cooling Fan running all the Time the AC is on .
As I also have a house in Las Vegas where it is Very Hot a lot of the year. However I well give the Factory System the First Shot

If you live in Vegas the mod to have the fan on whenever the AC is on is highly recommended - I think you will need it. If you do ever convert to R134a you will absolutly need it or you may damage the system from overpressure.
You have to remember that when the 928 was introduced cars looked a lot different and a single removable panel modular/removable element fuse & relay panel like this was quite a marvel - like something out of Star Trek.
Here is a picture of what a '77 Camaro/Chevelle fuse box looked like for comparison:
People look at the mass of grey wires on the back and think its bad. Actually making them as short and direct as possible looks crappy but is a good thing. Keeping it simply wired gave Porsche lots of flexibility to do YTY changes - and they did. Porsche didn't design this for owners to mess with - so they just used grey wires everywhere - this was a very expensive luxury car - if you could afford the car you could afford to take it to a factory trained technician... (so they thought - and it was probably true for the first 5-10 years) so a very reasonable choice.
The good news for us is that though daunting and intimidating - its all fixable - the modularity helps, you can change any connection, replace any terminal, swap out any fuse block or fuse terminal, any relay socket or any plug connector. Also excellent is that you can easily take the whole thing out and do any work needed in comfort in a chair at a table rather than laying upside down crammed into a footwell with your back in agony.
There is also expansion room built in for additional relays, fuses and connectors (there is always even a whole spare unused plug available)... Its actually great. A modern VW fuse panel with any issues is a throw away & replace the whole thing deal - and has no expansion opportunities at all...
So to me it was and mostly still is a great design - the biggest issue is that they are all now about 20-35 years old - so they are more brittle & generally more oxidized - so we need to be careful.
Now placing it right under the bulkhead penetration for the blower motor recirculator box with no drip protection may not have been the smartest move...
