Using a free ignition output for TACH signal to my old instrument cluster (which usually is fed from the coil)
Parts
- 5x 680 ohm resistors
- 1x 220uH coil (from rescue kit, black in shrink sleeve, looks like a barrel and has both connection pins at one end :-)
Wiring
Not sure yet.
For the moment being I am considering postponing this until I upgrade firmware to 1.1 branch and can use VEMStune + 7" touch screen as instrument cluster replacement.
