A much needed wiring adapter when you are upgrading to OBD-I (1992-1995 components) on a 3.2 or 2.8 liter engine. The earlier M50/S50 engines use two separate water temp sensors in the head, one for the ECU and one for the instrument cluster. Most of the 3.2 and some of the 2.8 liter engines do not have two holes drilled in the head for the early water temp sensors because these models used a combined water temperature sensor.
No cutting and splicing, no trying to find plugs and pins, no hack wiring underhood to worry about.
Turner also suggest using the TMS "3.2 in a 3.0" Coolant Hose Adapter ES3028184 to make your life easier.
