What pins did you use?

 

C16 Primary Sensor (Input)


And conected the resistors to Narrowband plug, it is easier than mess with the ECU cables, is hard to find the Ground Heater pin.

 

The wideband was connected and everything goes nice. the problem was the ESM. I will go to the dyno to see my A/F results, at ilde I have a A/F, 14.5:1


I mas this chart for those who is going to use the plx as a gauge. if you are using a Standalone (is compatible with AEM in their web page are the instructuions) You must connect the WHITE CABLE to the STANDALONE

Because is very hard to find the the primary Sensor heater ground connection, (the primary sensor heater output signal is easy) I conected the resistors to the female plug of the stock sensor (see picture to see which are the pins)

 

I will be installing mine soon....
