hi all

Got me a universal lambda sensor (4wire one) I know that the grey wire is an earth but there is two whites and one black wire, which way do they wire up to the loom as there is a Yellow/red wire, a Black/white wire and a plain white wire.

I've tried search but can't find out, Can someone tell me how its done as I need it done tomorrow ?

Cheers Dave

 

If you look at the 3-pin connector, one of the pins is gold/bronze.
This is the signal wire, which connects to the Black on the universal lambda.

The 2 whites are the heater wires which can be connected to either of the other wires in the loom as polarity does not matter for the heater element.

 

Cheers Scott thanks for the quick reply Will sort it tomorrow morning.
