Does anyone know how to install a air/fuel ratio gauge in a 2001 Tiburon. i need to know where to connect the sending unit wire(the purple one) in to the computer or O2 sensor. Thanks for all your help
I hooked mine into the O2 sensor. I believe its the one on the left header and I have a total of 4 O2 sensors on my V6. I am going to be disconnecting it this weekend to get it prepped for my trade in so I will tell you EXACTLY where it is.
I had a guy that did a tonne of N2O setups hook it up, but don't quote me where its patched in.
Your best bet is to weld in a new bung and use a dedicated O2 sensor. Attaching an A/F gauge to an existing O2 sensor can cause a <i>slight</i> reduction in the voltage output in the O2 sensor, which could cause your ECU to see a slightly lower reading than what your O2 sensor is sending. Remember, the output of your O2 sensor is less than one volt, so reducing the reading by 2 or 3 hundredth's of a volt will make a significant difference.

If you check out autometer's (www.autometer.com) site, they recommend going to the factory harness, and not to the O2 sensort itself if you can't/don't want to connect to the ECU, since at some point you will have to replace the O2 sensor.
