LC-1 install with DIYPNP on NB using stock O2 plug?
 

I am in the early stages of swapping a VVT motor into my '99. Part of this swap will be a DIYPNP and VVTuner (Same type of set-up I run on the track car). When I go to wire in the LC-1, can I use the factory O2 plug to provide power/ground to the LC-1 and signal to the DIYPNP? Looking at the wiring diagrams for the '99, it looks like there is a dedicated heater circuit for both +12 and ground, a shielded sensor ground and a signal back to the stock ECU. Has anyone wired up an apadter harness using the existing front O2 sensor plug and just plug that to the factory harness? My plan is going to be to power the LC-1 through the heater +12 wire, ground the LC-1 through the shielded ground and signal through the factory O2 signal wire. Anyone see any potential issues?

Wideband. Don't be silly.

I hate the idea of wiring and installing an LC1 controller in the engine bay.

Thanks for the valuable comment.

The way the LC-1 connects to the sensor, where else can you mount it? Aside from not liking the placement, do you see any issues with my plan?

I like wiring off the ecu loom, running sensor down through shift boot. If you need length, they sell a sensor extention loom. The controller can hang out safely under the radio.

I lopped off the connector of my stock O2 sensor and put it on my LC2. The control module is mounted under the dash and gives easy access for the serial port and calibration light. The heater circuit works great to power the sensor, but I remember having to probe the connector to figure out the polarity of the heater power wires. I don't remember why, maybe I was lazy in reading the diagram.
