Holy Grail Labs | Blade Fuse Box Upgrade Kit
Developed by Holy Grail Labs to address one of the biggest causes of electrical problems in your classic BMW—the ancient and unreliable torpedo fuses. This kit upgrades your failure prone and unreliable torpedo fuses to modern, reliable blade-style fuses.
ATTENTION: This kit requires the modification of the fuse box by removing the bullet (torpedo) fuse holders. Once the torpedo fuse holders are removed the new circuit board drops into the existing slots through the plastic.
