That resource does not include the version of 5 pin relay that VW used
for the fridge and aux battery relays. The VW relay has 2 pins labeled
87 and they are tied together permanently inside the relay. The relay
connects both 87 pins to the 30 pin when the relay is on. When the relay
is off both 87 pins are still connected together.

VW made use of this twin 87 version to simplify the kitchen wiring
connections but people don't always understand how to connect it. When
some people convert the fridge relay to be an aux battery relay they may
not realize that they are removing the protection afforded by the fridge
relay for the Dometic 3 way fridge 12 volt operation. Dead batteries can
result.
