I have a TR6 and 59 Healey 100-6. I have used the Classic Technologies fuse boxes in both of my cars to update the old and tired electrical systems. The Classic Technologies fuse box was designed for classic British cars and centralizes all the fuses, relays, and flashers into one small module. It is a very nice and well thought out unit to use, and work with. Here is a link to the website: https://classic-technologies.com/fuse-box.php. On the website, there is a link to video about the fuse box, a schematic, installation images, and more. Additionally, if interested, here is a video of it being installed into an Austin Healey.
