4 Wire O2 Sensor Wiring Diagram Nissan

The Oxygen Sensor used in this device gets very hot in operation. Do not touch the hot sensor.. 2.2.1 Single Innovate Device Relay Wiring Instructions5 . 3 Sensor. See the in the next section for a relay installation diagram. 3 The BLACK wire should be grounded to a solid ground source. The. Here's a guide on how to wire an innovate LC-2 wideband lambda/o2 sensor (I'll refer to it as WBL from now on). The WBL is a very useful tool to aid in tuning, especially when you get past stage 1 and 2 and parameters around the engine start changing to such a degree that the original calibrations will no longer be sufficient for a correct mixture and efficiency.

Page 1 When installed in the exhaust, the oxygen sensor MUST be connected and operating with the LC-2 whenever the car is running. An un-powered oxygen sensor will be quickly damaged when exposed to hot exhaust gases. Page 2 2. Sensor Cable Connector - Mates the sensor cable to the O2 sensor. 3. Wiring - The LC-2's wiring is very straight.. For the LC-1, wire the brown (analog out 2) wire to the MegaSquirt's O2 input wire. For the MTX-L and LC-2, the default analog outputs are reversed, so you'd wire the yellow (analog out 1) wire to the MegaSquirt's O2 input wire. For any LC-1 purchased after June2006, that should be all you need to be concerned with when wiring it up.
