VW Baywindow Bus - Fusebox Layout

The owner's manuals aren't clear which fuses are 8A and which are 16A and it varies from year to year. Bentley is even less clear and there is a mistake in the manual but the color wiring diagrams explain which fuses protection which circuits.

16A fuse locations are indicated in red at the top of each table.

There are twelve fuses in fuseboxes of 70-79 models but only 10 in the 68-69 models.
68-69 models only use 8A fuses.
Accessory means radio in most cases but can also mean gas heater in addition.
Fresh air fans were mainly available on non-US models for defogging the front windshield.

Wiring diagrams from Vintage Bus are hyperlinked.
