One thing that I've always been grateful for is the S13 service manual PDF that I got from Jez Horsham's website.
There's always been one thing that's annoyed me about it though - the wiring diagrams at the end are all at weird angles, upside-down, not in sequence, and on seperate pages. It's easy to understand why, it's because they were originally fold-out sheets.
So, here I present the fruits of my labour.
Two absolutely enormous PNGs which contain the ECCS wiring diagram, and the main car circuit diagram all stitched together. There are a few strips missing which I couldn't reconstruct, but hopefully they're not that important
