UPDATED: A diagram added to show current distribution.
One of the motivations for LINbus, both in general and in this case, is low-cost cabling reduction: To reduce the amount and length of cables throughout the vehicle. This has other benefits including simpler, smaller wiring looms that are easier to fit and to make.
And to maintain! I wouldn’t consider it if I didn’t think it’d make life easier.
Production cars however, largely fail to realize the full potential of cabling reduction because they still have centralised electrics, often with a fuse panel in one part of the car for all the lights, motors, heaters, etc. etc. Which of course means that those devices are all wired back to the one location
The MkV Golf has 3 fuse panels with the one at the end of the dash carrying 44 fuses. Keep in mind that each fuse needs 2 wires. One coming from the supply, via e.g. a switch or relay and the other going to the powered device. Are you getting the picture?
