*by D***B on February 11, 2016*

I got this for my Haltech PNP ecu for a 300zx. Haltech charges around $190 for the same sensor (HT011100) with a sticker on it. The only downside is this price doesn't include the plug... which is about $10 with flying leads or $7 without @ [...].I bought the adapters that go from this sensor to -6 AN fittings from getfast1.com, part number RUS 640853 "Push On EFI 6 AN Male To 3 8 Hardline Fuel Fitting Black LT1 LT4 LS1".The sensor has the pinouts labeled incase you were wondering and trying to find a diagram, Haltech doesnt have it on their website at this time. Looking at the sensor from left to right the pins are ( 12V - GND - Dig Out). Connect digital out to a digital pulsed input on your ecu. Calibration: (Hz / %)(50 / 0, 150 / 100 ).
