 Connect "GND to ECU" to the ECU's sensor ground, pin 24 (Green/Black) on a 1G ECU or pin 92 (Black) on a 2G ECU.  This is also present under the hood at the MAF, TPS, MDP and coolant temp sensors.
-If the sensor is a 5V sensor that draws little current, like a MAP sensor, connect its power, signal and ground connections to the buffer circuit assembly. If the device, such as a wideband, has it's own power and ground, connect only the signal wire to the device. Insulate any unused wires.
+If the sensor is a 5V sensor that draws little current, like a MAP sensor, connect the sensor's power, signal and ground connections to the input side of the buffer circuit assembly. If the sensing device, such as a wideband, has its own power and ground, connect only the sensing device's signal wire to the input side of the buffer. In either case, you still must provide +5V and GND to the buffer circuit and you must then insulate any unused wires.
