Im getting the stack wideband one this week but there are a few wires im not 100% about.
There is a WOT (wide open throttle) one but it says to be used with the WOT switch, that isnt supplied. Is that possible to get one for the throttle body?
If you dont have one it says to earth it, so really does it matter if you use it for its real function? I have read the instructions on the page suppleid from merlin motorsports: http://www.merlinmotorsport.co.uk/images/instrumentsl/st3401instructions.pdf
There is also a blue and blue/black for data logger. It says "A 0-4 Volt analogue output can be connected to a data logger or to an ECU to provide real-time closed loop feedback for improved mapping." Is it essential to have that connected up, or can it be wired to the ECU?
Or if anyone has got this installed any help would be good.

Thats an identical spec to my Autometer one. There is a WOT switch on the G40 throttle body you can hook up to. The two data output wires are for feeding in the values for live mapping hardware/software. Just leave em tucked up behing the dash until needed.

Thanks!! Did you wire up your WOT?
Not sure where it goes too, but wil have a look.

got my gauge today and was wondering what to do with the wiring harness that is used for the lambda?
The gauge comes with its own wiring harness for sensor but knowhere for the standard harness to connect to.
Unless it doesnt have to connect up, but i thought it ran to the ECU?
-
Am i being stupid, do you have to weld in the bung that it comes with so you run 2 lambda's? :-\
-
Yeah Jezza, you'll need to weld the supplied bung in to run the wideband Lambda.

Ahh thought i was being stupiud!
