Volkswagen T3 fuse and relay list, for early and late T3

The T3 model has been produced for a relatively long period of time. Therefore changes and improvements have been made during its lifespan. In this blog we will show you the fuse and relay list for both early (before 1985) and late (after 1985) fuseboxes. This will help you with any electrical work you are going to do. Make sure to check the right table depending on the build year of your van.

The early model T3 vans are equipped with the old VW style ceramic fuse box. Vans that are produced after 85 have a different type that can be found in the next paragraph. In the image and table below you can see the location and use of each fuse / relay and what they are used for:

VW T3 fuse and relay list >85 (late)

At the beginning of the 80’s VW started to get rid of the old ceramic fuse box and replaced it by an improved version. This new version was named “Central Electrics” and has been used in many different VW types including the VW T3 from after 1985.

In the image below you can see the location and use of each Relay and Fuse. Some locations are not used in the T3 but are used in different models that use the same electrical system. If you want to add additional electrics you can do it in those free spots.
