I want to say it was around 20 bucks for the kit was all the different fittings. The LT5 sensor's in an easy spot to get to to hook up the mech gauge to.
Just because the sensor doesn't look bad and is working, doesn't mean it's calibrated correctly. I tried 3 or 4 different brand sensors before I found one that was calibrated properly for the car and matched the mechanical gauge.

I'll disconnect the plug tomorrow and see what it says.
