Ive searched and searched and I can't find the answer so here I am asking...

Which wire is the signal wire coming from the O2 sensor that I would need to splice for an Air/Fuel gauge??

Thanks

 

You can't use the stock O2 sensor for A/F. You will need something like the Innovate LC-1 which has two outputs (0-5v, 0-1v). You can replace the stock sensor with this one or add another bung for the new sensor. If you go the replacement route, you will need to cross-connect the heater signal from one of the other sensors because you will no longer have that signal if you replace the sensor.

 

+1 as what is said above as our 2003's do not have wideband capability.

 

ahhhh thank you
