Hello peeps!

I've just received my new lambda probe (cheers "grumpy"), and it's going in later today.

Anyway, it's a BOSCH LSM11 4-wire one....stock is 3...with the "heater" +12vdc, ground and signal....umm...I heard the 4th one on this LSM11 is an extra ground...what for?

And why do they have to use weird colours? I've got 1 black, 2 white and 1 grey wire coming out of it...

/J

 

mine has four wires (MY01)
i had been told that the the two white wires are a loop to/from the heater- but maybe someone will correct me!
hope this helps you-
simon
ps black = ground, grey = signal (?)(mine is blue)
