I had an additional bung welded on for the wideband...that would suck if it turned out I didn't need it, LOL
Use the connector of an old O2 sensor. You can use the stock harness to power the LC1 and ground it, as well as send a narrowband signal to the PCM while sending the wideband output to your scanner of choice.
There's a diagram in a post somewhere (joecar ?) of the pinout of the O2 connector. Out of the box, the LC1 yellow wire is narrowband output, red wire is +12v ignition and blue wire is LC1 ground. Green wire is analog ground. All those can be connected to the wiring harness.
LC1 Brown wire is wideband output, LC1 white wire is wideband ground, run those to HPT EIO white and black respectively (or whatever else your are scanning with).
Let me see if I can locate that picture of the pinout.
You might also consider how I ran mine though - cig lighter adaptor to power/ground LC1, same LC1 brn/white to HPT EIO, not using narrowband output because I have the wideband sensor installed in a seperate bung.

would need a seperat bung still but you could still use it to compare against teh stock narrowband
