   I have a air/fuel ratio gauge that I need to wire up. these are the instructions
   
   1 Connect RED and WHITE wires from gauge to vehicle ignition
   
   2 Connect BLACK wire from gauge to Battery (-)
   
   3 Connect GREEN wire (AF signal) from gauge to either :
   
   ECU pin which has the AF signal or to the Lambda sensor
   
   narrowband wire (0 - 1V)
   
   
   so which colour wire is the narrow band wire from the lambda sensor on a mk2 (there are 4 wires)
   
   and which wire is the ignition

   get a multimeter on the wires mate, says it makes 1 volt by what you have wrote so get the engine running and look for the wire that puts out 1 volt

   search the forums for past convo's on this subject and after looking for like half hour found 1 that says the narrowband is the black wire.
   but still worried about cutting the ignition coz of the imobiliser

   so you can just use the live wire from the radio, dint know that.
   I might keep the gauge then if I dont have any interest on the for sale section.

    no need to actually cut the wire, just strip some of the wire back and solder then the connection will not be lost.

    when i had mines. it was red/black - pos/neg. i took that from behind the sterio. the grey wire i had left on the gauge went to black wire on the lambda sensor.
