After what seems like an eternity, finally finished the install of the fuse and relay modules into the MK RX-5. This was my second attempt and very pleased with the result.

The key was spending several hours drawing the schematics for the fuse and relay holders, and planning where to splice in additional wires to avoid multiple cables in one crimp.

Here's a few pics 🙂
