Parasitic drain - What type of relay is this?
It appears that your car has a configurable option which, on some models, will give additional functionality to the circuit in question. For example, the circuits on pin 87 may only be switched on when 85 is pulled low (energising the coil), say, when the auxiliary power is on or remote control is an option. (I have no idea what's actually happening).

On cars without the feature a shorting link is added. Mounting this in a standard relay case makes sense as the link can be fully isolated and it's just a part change for each model of the car. Why the "coil" is shown as 12 V is anyone's guess but it may be part of a template on a laser marking or thermal transfer printing system and it's just not worth making a special case for this module.
