On the 7M diagnostic box, there is a single Ox pinout. on the 1JZ, there is an Ox1 and Ox2 pinout. All I did for the A/F on the 7M was stick the wire into the Ox port to test the gauge and it worked fine that way, but on the 1JZ, neither port it registering. one port causes the gauge to be blank, and the second just makes it have a solid green LED. Any ideas? Maybe I am just not making good continuity in the pinout.
