I have this computer http://www.kstuned.com/products/the-black-ecu its a jdm computer.Im trying to connect the ngk wideband up ive read the plx wideband setup on hondata website but it says white and grey wires but the ngk comes with a yellow and brown. What does the yellow wire need to be connected to and where does the brown wire go to. Any help would be appreciated.

 

you only need to connect one of the wires... IIRC, one of them is 1v output, and the other is 5v output.

What are you trying to accomplish by connecting the WBO2 to your ECU? are you looking for narrowband emulation or wideband datalogging?
