The Vanagon Tachometer Fixer may look like an ordinary relay on the outside - but on the inside it's magic! The module eliminates the need to take your Vanagon tachometer out and modify the resistors. You simply wire power, ground, Tachometer signal, and Vanagon tachometer wire and you can see your revs. It's small enough to mount in the Black Box or near your Subaru ECU.
The Tach Fixer is only needed on 1986+ Vanagons - The earlier tachs work directly with the Subaru Tach wire.
