Lambda Sensor Wiring
Hi Guys,
Just got to wiring up my Lambda a sensor and stuck on a couple of connections.
So 2 wires are heater, ground and ignition.
Other 2 are Sensor Signal And Earth.
But the Black top ECU has two pins of the ECU, pins 60 is called "HHO2S 1 signal " and 93 is called "HO2S 1 control"
Anyone know which is which?
Cheers,

Hi guys,
Lots of searching seems to point to the following, can anyone confirm?
Original Pin 1 - Gn/Ye (Power hold relay) = Heater + (universal Sensor White wire)
Original Pin 2- Bk/Ye (Pin 93 HO2S 1 control) = Heater -(universal Sensor White wire)
Original Pin 3 - Bn (Sensor Common Spliced in to pin 91) = 02 Signal Ground (universal Sensor Gray wire)
Original Pin 4 - Wh (Pin 60 HO2S 1 signal ) = 02 Signal (universal Sensor Black wire)

There are two circuits. The heater and the sensor.
12v to the heater the ecu controls it by switching the earth.
The sensor has the sense wire and a common sensor earth.

Hi ya,
Does my pin out look good?
The Universal sensors are not good at matching up etc?
