Last year while researching some fog light stuff, I stumbled upon driftnastyjzx100's flickr account that had some cell phone pictures of the wiring supplement for the '92 Silvia. Some of it was very hard to read due to the graininess of the images. So I decided to rebuild the diagrams in a vector program and get them as close to 1:1 as possible with the real deal. It took me a while, but I was able to recreate the W-1 chassis wiring and W-2 ECCS wiring diagrams and then transmission them. But I couldn't stop there. The images of the supplement had left out the W-3 door and W-4 Air Conditioning diagrams, so I recreated those based off of pinouts I had from the W-1 diagrams, the USDM diagrams, and lots of images of wiring harnesses. The auto air conditioning wiring was a particular beast to sort out. I watched through Junkyard Dave's install video to get stills of the harness and his pinout notes as well as a TON of for sale threads trying to identify pinouts for confirmation as well as using the 1996 180SX electrical supplement to fill in a few blanks (and ultimately the '96 supplement has different wire colors. so yay my sanity!). I tried to make the transmission more than just transmission. Hopefully these help some of you who have imported JDM cars.
So without further ado, here's the diagrams. The images are huge at 7746x3300, so I can guarantee that NICO will shrink them to fit your browser. You can either download the image or right click and open the image in a new tab. I'll also include some google drive links at the bottom that have all of them in zip files. I might also consider doing the harness layout pages as well if people want them.
