Hi everyone,
i just wondered if anyone out there can help me at all,i have bought an AUTO GAUGE AFRLEDSWL-20B 2" AIR FUEL/RATIO GAUGE but i am haveing some trouble trying to find a wiring diagram or any body that knows the correct wire to chop into,from looking at the car (legacy 2.0 gt twin turbo,BG5,1994)it has 3 sensors on the exhaust system,one in the cat which looks like a temp sensor and has 2 wires,one a bit further up towards the engine on the left side of the exhaust (left side form sitting in the car)which also has 2 wires and looks like a temp sensor but then on the same side further up on the system (on the complex bendy part of the downpipe) which is a bigger sensor which looks like the correct one and this has 3 wires going to it.
On my gauge i have 3 wires,black,red and grey and in the instructions it doesnt tell you where the black and red go so i imagine that these are just the live and earth to power gauge up,it only says that the grey wire has to be connected to the O2 sensor signal. and i dont know which wire this would be on the car,can anybody please help......Thanks for reading.
