Cool!! That is good to know.
Now I need to know if the color coded wires are the same for a Corvette, Firebird and GTO. I'm having an issue with 02 sensor simulator and the only thing I found is a sensor simulator that is for a Firebird.... The plug is square from the Firebird but flat or straight for the GTO. If the color codes are the same, I'm gonna' splice it with the sensor extension I originally got with the L/T headers.
