I would have at a guess the O2 sensor input?
Ideally you really want a wideband one one an not just a air/fuel guage going off the narrow band sensor

 im sure it was the black wire i had mine conected to 
It should sit at lean untill your booting it and it will move up
It is also the same guage that i have

I dont have my car with me right now hence why i cant remeber what wire i had it conected to but i was sure it was the black 1
What does it sit at when conected to the black wire? it must be a good conection to recive a good reading also must be well earthed i remember having probs getting mine to read correct

How do you mean it just sits at optimal? it should sit at lean and it will only move when your out driving lol

its does it checks when i turn the ignition on goes round the gauge and back even with car not runing but with ignition on it just goes back to optimal with one led showing start the car does not move of the same led on the gauge drive the car does the same just stays on the same LED light
such a puzzle lol

How do you mean with the ignition off it stays on the leds should only light up when the car is running
It will only move when you are really booting it lol makeing the mixture higher so the gauge will move up

A narrowband gauge isnt really much use anyway but if you want to get it going then you need to a multimeter to get it right. the 3 wires to the lambda gauge are ground, +12V and signal. The ground and the +12 are easy to find, the signal wire should have anywhere from 0-1V on it with the engine running. If youve got the signal wire correct and its still not reading right then take the earth for the gauge from the earth to the sensor.
If you want something usefull then you need a wideband lambda setup, Ive got the LM-1 which i connect up when i think i have a problem but there are others. You need a new sensor and the controller and a gauge. The controller is programmed to talk to the ECU in the same way as the standard Lambda would so the car doesnt know any different but the gauge will give you an accurate reading as rich as 10:1

Right people had a day off today to sort this out but still not working !!
Got the mulitmeter on it today and this is what i found out
there are 3 wires on the c20let landa sensor
1 black
2 white
Black Wire being singal
2 whites are earth and live
After geting the mulimeter on the wires today this what i found
Signal black wire 11v volts !!!!
White wire a 12v volts
2 White wire (Middle of plug) was the earth !
Is it me or is there somthing roung with the signal wire runing at 11 volts????
many thanks

Yep shouldnt be 11 volts at all, looks like your lambda sensor might have had it. you did have one lead on ground and one on the signal when you tested it didnt you? (dont mean to insult your intelligence, just not sure if your clued up with electronics)
