The 5th pin labeling of various OEM VW 5 pin relays does not comport to
the diagrams in that link.

Use of a generic 4 pin "Bosch type" means that the 4 pins are in the
same orientation on all of the relays that follow that standard and are
labeled with the same numbers on each of the pins. Many oem relays don't
follow that standard so the user must have some better idea of what they
are doing if they use something other than the standard 4 pin.

The standard "Bosch type" 4 pole relays are used in every VW for decades
so pretty easy to grab at a yard and I have many of them from various
VWs, OEM. VW stamps them as 53 and 24. I use a lot of the later 53 ones
for various uses. There are also OEM VW 4 pin relays with other numbers
that are the functionally similar except for larger male spades on the 2
high current pins so different wire ends are needed on 2 of the new
short wires. Examples of those would be VW stamped 18 and 111 types.
