Success. At least some progress.
I almost almost almost cut the green wire 7, to disable ews on my 1994/10 car. I checked the door for the manufacturing date.
Anyway before I cut it I was like eh - lets unplug everything except the starter and alternator wires. I also cleaned the surface of those wires. And voila, turned key and heard the starter crank the car for a second. Only a second since I didn't want the fuel pump pumping gas everywhere since everything is unplugged.
So either one of the plugs into the engine messed things up or cleaning the starter wires was all that was needed. I'll update as soon as I test each one.
