Little things — logbook Toyota Corolla 1997

I solved the issue with the tachometer, sorted it out with the circuits, and realized that the tidy is all the same, but at the same time you need to understand that the signals are also the same, looked at the signal with an oscilloscope, there is an extra negative pulse that interferes with the tachometer, there will be time to disassemble the tidy and take a photo of what you need to solder .

when assembling the wiring, I clicked a connector that connects to the checkpoint to turn on the light in reverse))) needs to be restored.
