I had a fire behind my cluster (the wiring harness). I've replaced the wiring and found another cluster from a wrecked car. Most of the old cluster survived and I want to transfer the mileage over to the new cluster. Does anyone know which chip stores the mileage info?

Thanx for any Help

Or a place that I might find a schematic? I already tried Tanin Electronics and they wouldn't give me the info. Guess they thought I was going use it at a car lot or something.

 

This is for an ES300 but yours may be similar.

Thanx for the response. It was a cool video but the chip he was refering to was an 8 pin chip. Unfortunately there are no 8 pin chips anywhere on the sc300 circuit board.
