My Toyota corolla 1996 model was using 89661-
1A380 4AFE computer box which burnt, which
other computer box number can I I use since I'm
struggling to get the same?
You can’t, the numbers must match. I suggest finding a parts store that has an R&R service, you take your computer to them, they send it out and have to rebuilt and programmed and then they send it back to the store and you pick it up. But before you put it in you need to find out why it burns up, over voltage, bad grounds, shorted reference voltage wiring, etc.
