The wiring information for the gauge says to use,“a ground close to where lambda controller is grounded.”
Is this the sensor ground or the heater ground?
Also if trying to use the LED with the controller, where does the LED ground go to?
Ground to where the electronics ground of the wideband controller is grounded.
For Spartan 3 lite v2 the long lead connects to the blue wire, the short lead grounds to anywhere you want.
Thank you
Has anyone come up with a simple LED mounting or installation solution?
