Wideband lambda- which wire is the signal?

[Jonny Grigg]

Hi guys,

I have an LM1 with a Bosch(?) 5-wire wideband lambda. I want to splice a connection into the signal for the nitrous system controller, but I have the following wires: black, red, white, grey and yellow. Instinct tells me that the signal is the black one, but I am not sure- any ideas?

Thanks

Jonny.

Hi Jonny,

it is a Bosch LSU 4.2 normally.
Have a look here:

But as far as I know it is not working to splice the signal....
But you can have a try 

Cheers,
