This is a going to be a big-ish update, lots of photos, so please click through to see the rest of the post.
I spent the last couple of days building my custom fuse/relay panel. I've been looking forward to this part of the build 😀
I went to the local plastics engineering shop and got them to cut out a piece of polypropylene for me. This is what I used for the "panel" part, got it pretty thick to make sure it was sturdy and adequately insulated from the car body.
The completed fuse/relay panel, it got a bit messy where the large terminal block is. The purple Deutsch connector at the bottom powers the injector and coil +12v and the braided cable go into a ECU connector for power and various outputs for fuel pump and fans etc...
