ok, I've laboriously traced out each connection from the connectors to the items they connect to. I did this by drawing a different colored line on each trace in the scans of the circuits.
I don't have any official docs (like a factory service manual, or factory wiring diagram), so in the absense of the correct names for the connectory, I simply named them C1 thru C5, with C2 being the 3 pin ABS related connector, counting from left to right with the connectors at the top of the board from the back. In other words, from left to right in the pictures I posted in the previous post. I numbered the pins the same way, from 1 to whatever.
Here are the changes:
C1 pin 9: original goes to: IG+ for Fuel and Temp gauges, and these lamps: CEL, Windshield Washer, O/D off, Oil, Cruise, Seatbelt, Brake. New one goes to: IG+ for Fuel, speedometer, tachometer, and temp gauge. These lamps: CEL, WW, O/D, ABS, Low Gas, Brake, Seatbelt, Oil, Cruise
C2 pin 2: original goes to: C3 pin 2, Rear Defrost Lamp, odd circuit behind speedo, L and R turn signals, High beam. New one goes to: C3 pin 2, odd circuit behind speedo, L and R turn signals.
C3 pin 10: original goes to: SE on speedometer, E on fuel gauge, C4 pin 2. New goes to: C4 pin 2, C4 pin 1, SE on speedometer and fuel and tachometer
C3 pin 11: original goes to: Rear Defrost. New goes to Left Turn Lamp
C3 pin 12: original goes to: Left Turn Lamp. New goes to: high beam other leg.
C4 pin 1: original isn't connected, new is: C4 pin 2, C3 pin 10, SE on speedometer and fuel and tachometer
C4 pin 2: original is: SE on speedometer, E on Fuel Gauge, C3 pin 10. new is: C4 pin 1, C3 pin 10, SE on speedometer, fuel, tachometer.
C4 pin 9: original isn't connected, new is: TAM on tachometer
C4 pin 14: original isn't connected, new is: IG- on tachometer
C5 pin 9: original is +B on speedo, door ajar lamp, new is: +B on speedo, +B on tach, door ajar lamp
I don't think I did any damage with the incorrect cluster in. However, I'm hesitant to try it in the car again. I'm keeping my eye open for a different cluster
I'm wondering if this cluster didn't perhaps come from a different model of toyota. Does anyone know how interchangable they might be? I know the ebayer said it came from a corolla, but you never know. Of course, a different model year might explain it.
