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 3D printed module support certainly made it more straightforward to crimp the connectors and insert them into the modules. Given the amount of modifications I've done to the MX-5 loom, it was very pleasing to connect the battery and things all came to life as they should!

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 🙂

Pleased with the bulkhead and scuttle fit 🙂 !
