[Supras] O2 Sensor + 3 inch elbow

[Sean Cavanaugh]

my old supra was running an Innovate LC-1 wideband which has 2 programmable 
outputs. default is one wideband and one narrowband. I fed the narrowband to 
the stock ECU and it LOVED it because it's a much more precise sensor so the 
voltage stepping was a bit tighter.
