So, for example, when looking at the tachometer on the schematic, the three bottom wires are numbered 31, 15 and 1 and are not circled. those same wires all have the number 20 at the far end and those 20s are circled. I have no idea what any of that means.
The red #30 coming off the fresh air fan relay has a damn circled 11 right in the middle of the line before it gets back to fuse #12. TIA for the education. |

31 is ground. Pin 31 is consistently used on other elements as ground. For the tach, pin 31 goes off page on reference 22. Reference 22 is connected to ground point B.
15 goes off page on reference 21 . Reference 21 connects to fuse 9. This is 12V power for the tach. 1 goes off page on reference 23. Reference 23 connects to the engine relay board on cabin harness pin 7. Pin 7 connects to engine harness pin 5 which connects to the ignition coil on the NEG terminal. So in general, 31 is the ground for the lamps, 15 is 12v power for the tach, and 1 is the signal from the coil to drive the tach. Did I pass the audition? |
