Hey guys, does the 07 Hemi Ram have a Wideband or Narrowband O2 sensor??? Trying to hook an air/fuel ratio gauge, however I've noticed some weird voltages coming from the O2 sensor...

Ok good deal, however I'm looking to hook up the A/F ratio, plus EFIE (for my HHO booster) to the Stock O2 sensor, and I need it to be a narrowband, so if that thread you sent me to is true for the 07 models also, then I have a narrowband sensors, which is what I need. I have 4 wires going to the sensor, 2 white wires, 1 grey wire, and 1 black wire (these are the sensors pre-cat). Does anyone know which one is the signal wire that goes to the computer?

 

Nevermind, pointless thread, our O2 sensors are 5 volt, which mean my stuff won't work anyway...
