Hey all, recently picked up a 2003 350z with less than 100k miles clean title as a project car, the only issues are electrical. I have had it for a little over a week now and I am coming on here to see if anyone can give some advice. When I finally got power to the car (positive connection was broken that led to the fuse box) I turned the key and only got a few lights to come on i believe it was airbag, battery, and another i cant remember but no check engine but the headlights turned on and the radiator was on full blast. The car would not crank so I checked the clutch/brake buttons underneath and the rubber stops were broken off so i fixed that and still no crank. Checked that every fuse was fine and took out and checked the relay so that everything worked which it did. I even pulled out the ipdm and took it apart to check for broken solders which i couldnt find. fusible links are fine as well.
The last option I came to was the ecu could just be bad so when I took apart the passenger panel to reveal the ecu is when I came upon this absolute behemoth of disgust. Several wires unplugged with the ecu dangling by two zip ties! I cant seem to find anything to support me tracing all this wiring to where it is supposed to go so I was wondering if someone was able to send me a picture of how their ecu is setup and what wires go where it would be a huge help.
attached is the picture of the mess of wiring minus the ecu i took out
