A wee help with wiring a new gauge

Hay guys, I have a new air/fuel ratio meter and I’m a bit confused with.

It has to take a reference signal from the lambda sensor (oxygen sensor) in the exhaust.

Now, the k11 has a three wire sensor, one positive 12v for the heating element in the sensor, one negative, and one that sends a signal to the ECU that only goes up to about 2v.

Can anyone help me identify the low voltage one. If I get it wrong, it will fry my new meter.

Any advice is appreciated.

nope, never needed one.

I thought id ask and see if anyone knew first before shelling out for one unnecessarily.
