I bought a air fuel ratio (52mm Depo Racing Super White/Amber Digital Air Fuel Ratio Gauge) and it did not come with an O2 sensor and the instructions make it seem like it can wire into the ECU. My question is can I wire this gauge into a wide band O2 sensor to this and where can I get an o2 sensor and connector?

Congrats you have a narrow band sensor. You can see if your stock OE 02 sensors are cycling.

You should have gotten this

Unless it comes with a wideband sensor it's just relying on your stock narrowband o2 sensors which won't tell you your actual air to fuel ratio. Any decent wideband setup will start at around 180 or so.

That gauge is made for the Bosch LSU 4.9 WBO2 sensor which AFAIK is the best on the market today. It can read fuel ratios for 8.0:1 to 30.0:1. But u need to get the correct Bosch WBO2 sensor for it.

It has (takes) a 0-5v output (input) that will not work with other HEGO sensors. My google shows Bosch LSU 4.9 WBO2 sensor and connector for < 100 bucks: http://www.wbo2.com/lsu/sensors.htm.

I dont know why u didnt bother to look at the Depo Racing w/s and info????

I just assumed it was a wide band and came with everything. ... not a very smart purchase model I know.... The gauge has great reviews and i really liked the looks of it... so i can use it like a wide band if I buy this sensor?

No, you can't use that wideband sensor. The instructions for your gauge clearly state 0-1v range for a narrow band sensor.

If this is the 52mm Digital Air Fuel Gauge you purchased

Here's the install instructions for your gauge

Vettzilla, just find the part number on the gauge u bought and look it up on the Depo w/s: http://www.deporacing.us/. Next find the sensor it works with in the product literature. Thats how i did it using your description but the trolls on this site dont care how much of someone else's money they waste (time and effort too). If someone wanted to give u useful information they would a visible profile to share.

Hope this helps and good luck.

Well I am returning that gauge and picking up this wide band gauge (Innovate Motorsports 3796 DB RED Complete Wideband Gauge Kit (2 1/16 52mm) with LC-1, O2 Sensor, Bung and Plug)

I bought the LC1 without gauge years ago and it has worked well for me. I only data log with it so that's why I didn't need the gauge.
