The folks at PSI are probably a lot more familiar with the instrument cluster wiring than I am but my book shows the break between 94 and 95 models. All models are listed as white wire for tach and dark green for temp gauge. The only difference shown in my book is the speedo wire is light blue/black on earlier models and dark green on the later ones. I'd be afraid to bet on my manual as it's not a factory service manual but you never know. I'm sure you've seen posts on here about the need for an additional resistor for the tach, maybe there is 2 dark green wires and they are switched? Just a thought.
