The speedometer out of my 92 SC300 will not function, nor will the mileage light up. I got another working cluster out of my brothers car (92 SC300) and the speedometer did work as well as the mileage lit up, what do I need to replace for my cluster to work? I don't want to change to another cluster I'd like to keep the correct miles on the car.

 

Replace the cluster. Motherboard main chip that also holds the mileage, is dying.

 

Can I get a replacement, other than a cluster?
