In order for your stock computer to your WB02 as a narrowband the analog 1 wire has to be connected to the signal wire on your stock O2 harness but there is a tan wire that needs to be grounded.. Ed Blown Vert and I were stumped and most of the diagrams hinted but never exactly said what to do... Once I grounded the tan wire EFILive was able to read it... So for anyone that wants to put the WB02 in the front O2 bung and be able to use it as a narrowband there is a definitative answer... =)

I directly connected as follows:

LC-1:yellow --> NBO2:B ppl
LC-1:green --> NBO2:A tan

Both of these must have a connection (whether A is direct from LC-1, or via ground) for the PCM to see the signal.
