Hi all, can anyone tell me where i can get a, (02 narrow band sensor, the one with four wires) cheers.

Narrow band is std on most cars. Wiring = 2 whites 12v and earth grey and brown to ecu. loads on ebay.

I found this place ages ago - no experience of their products but it's a place to start.

Standard wiring for a European or US 4 wire sensor is

Black = signal output to ECU
Greay = Signal ground

White Heater12v power
White Heater ground

(White wire are obviously interchangeable)

Gendan website is the font of all knowledge on Lamba sensors
