AFR gauge wiring
hi just got a nice swoosh air/fuel gauge to match my other gauges. not sure how to wire this one up so wouldnt mind a bit of help 
the gauge had 4 wires coming from it, a red,black,green and white. i know what they are for, red is acc, black is ground,white is batt+ and green is signal. what i need to know is where the signal comes from? ive searched and it seems its connected to a wire coming from the ecu? if so... which one?
the car is a my98 uk turbo wagon.
any help greatly appriciated!!
cheers all

I'm not 100% sure about this one myself, but, I was under the impression that the signal wire goes to the lamda sensor. I hope so anyway cause I'm fitting an AFR gauge soon too.
