I'm trying to wire up a Innovate LC-1 Wideband Oxygen Sensor and from what I gather I can wire it directly into the existing oxygen sensor harness that plugs into the factory narrowband oxygen sensors. It's for my Megasquirt setup.
How can I test the factory oxygen senser harness to decipher which one is giving me +12V, Ground, and Signal wire? There is 1 black wire and 2 white wires. From what I gather, black (signal), white (+12v), and the other white (Ground). Does the body of the oxygen sensor serve as a ground?
I have tried to find which one is power by using a Multimeter, 1 lead on the battery ground and the other probing both of the white wires, key on and engine running, and still have found no voltage.
Is there something I'm missing or is there no +12v being supplied to the oxygen sensors? Do they need to be connected for the +12v to be detected or can I unplug them and probe the connector like I have been doing.
I have been doing this for the past 5 hours and my head is spinning. Any advice will be appreciated!!!
