hi just a quick one want to rig up an afr meter to my cossie
already have the exhaust manifold drilled and tapped for my lambda

i have a golf gti bosch sensor ( 4 wire) heated i think will this be suitable ????

my afr gauge has 3 wires
red --- i assume is 12v live ???
black---- i assume is earth ???
and has a grey wire which i think is the signal wire from the lambda ????

my question is how do i wire it all up to the lambda ????

the lambda has 4 wires
two are white ??? one grey and one black ???
