Yep it's the fan relay. 450/500w fan relays are mounted on the A post. 200/300w fans use relay 5

So what purpose is the relay no. 5 then? There is one present there also!

And that metal link bar that is between the two cross headed screws with the heavy red wire on them, could that be a dropper resistor for the lower speed operation of the fans 2 speeds ?

Thats a fuse. On my US Vanagon GL the fan resistor for the lower speed is behind the headlight.

Def a fuse.

No idea.
Bridge out terminals 30 and 87 you can then tell us what it does.

Yes it is a 50A strip fuse.

Nowt! Tried it with ignition on and off. If it is a second stage fan relay perhaps 30 doesn't become live until the main relay 70A operates. Can't be a**ed to get that 70A beggar out again to jump that at the same time to check.

If you had checked it with a test light you would have seen 30 was live.
