    I have a 2009 Ultra and am trying to install the Dobek TFI. I have the injectors installed but cannot find the front and rear o2 sensors. My manual shows them together on the right side. I found what I think is the rear one but not the front one so I am not sure what I have found.

    Looking from the left side of the bike, the O2 sensors are located close to where you pipes go into the cyl. heads. Then just follow the wires down,the frt. one plugs in behind the cross brace on the frame down tubes just below were you see the sensor. you will have to cut the nylon ties to unplug the connector. The rear senser plugs down by the starter on the right side of the eng. behind your oil filler cap.

    Lefty; did you locate the O2 sensors to finish your TFI install? Luckily I was changing exhaust so mine were off bike (easy) & I plugged w/bung plugs...
