So, the mileage is not recorded and stored in the ECU? Its stored in the cluster itself? Also, why would the temp display E? Do I not have that wire that reads outside temp?It displays the outside temperature. NOTE: if you want to swap in a cluster with a tach, it will work - just plug and play - but your mileage readout will be different and the temp will display -E-.
Nope - mileage is on the cluster itself - not a deal breaker as you could simply transfer the speedo from one to the other. Correct on the temp - models without the tach as OEM are missing the thermistor that measures temperature.So, the mileage is not recorded and stored in the ECU? Its stored in the cluster itself?

Is there not a way to install the missing thermistor? I'm guessing that the wiring harness would still have the wire needed for the thermistor. Where is the thermistor usually located?Correct on the temp - models without the tach as OEM are missing the thermistor that measures temperature.
That could be it; since it is not connected to anything.
My concern is that it might be for fog lights or something else I haven't even thought of. However, it does appear to be in the correct location for the thermister fish mentioned.That could be it; since it is not connected to anything.
Well, years ago I had a ford probe, and I went nuts with "upgrade" and "tweaks". Granted, the mazda 2.2L Turbo engine was fun, but I reached a point where I had more projects going on than I could keep straight, and the car was in a bazillion pieces, and I never did get it back together. At one point I had 3 of them (a parts donor car, an engine donor car, and the one I was trying to get back in shape). Then the county came along and said I was in violation of the junk vehicle laws, and off to the scrapyard they went.That's great news that you now have a working tachometer.What are you doing with your old instrument cluster?
The instrument panel will probably not work for me, I was just curious as to what you would do with it.Well, years ago I had a ford probe, and I went nuts with "upgrade" and "tweaks".

I've decided I'm not going to go nuts with this vehicle. I want to keep as close to stock as possible in most cases. So when I need to make a hole in a plastic panel, I first buy a replacement panel and put the original in a safe storage place, so I can put it back if I ever need to.
My plan is to hang on to the original instrument cluster for this reason. However, I might get rid of it on ebay after several month. I'm just not sure yet...
I did end up re-using the speedo from the original panel, and I transferred all the lights rather than painstakingly testing the lights in the new panel. Also, the new panel has a problem with the left turn signal indicator not lighting. If the highbeams happen to be on, the left blinkers cause the highbeam indicator to blink. I don't know if the original panel had that problem. I'll track it down eventually. Hopefully something super simple.
Would an 8th gen instrument cluster work in your 7th gen cars?
Oh yeah, this was also the first instrument panel swap I ever did on a vehicle with no speedometer cable.
I appreciate the scans, they've been helpful.Clusters from the same generation and market (ie. 8th gen (1998-2002) for North American market only) - are plug and ply. There are some differences - but they wiring is largely the same between the two (connector wise).
I've got some scanned FSM diagrams on my Photobucket site - might be useful:
Thanks for the very detailed wire tracing, even that is covered in that detail in the Factory service manual without breaking out the separate wiring diagram.
I think that within the same year clusters can be different for different models, such as CE, LE, DX, etc.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.
