Hi Guys,
Fitted three gauges today but having some trouble with the Air/Fuel Gauge.
I have to connect the Singal wire of the gauge to the signal wire of the lambda sensor.

I looked at the lambda sensor and its just two white wires and a black wire. So at the moment im stuck as i cant tell witch one of the three is the signal wire.

Also the instructions say not to use a multimeter on the lambda as it will damage it.

Any ideas.

I heard that the non wideband AFR gauges are no good & the gauge just gives incorrect readings?

So am I right I'n thinking the signal is one of the white wires ?

Signal wire is black, the two white ones are the heater circuit.

as above black is signal wire. nearly all (if not all) lamda's use two white wire for heater whether they be 3 or 4 wire type

if you use JGM`s web site for the pinouts,

you want B136, terminal 21 for the signal connection in the passenger footwell.
