Sorry to dig up an old thread but I am planning to install the PI PTU on my 2013 non-PP SHO. Did anyone ever find out if the non-PP harness has provisions for the PTU temp sensor? Also, would I need a PI PCM in order to get the code that monitors service intervals for the PTU fluid?
Option B is just add a trans temp gauge with a generic oil temp sensor in the factory temp sensor port and manually monitor temps.
