LC-1 hookup question

[PSWired]

Is there a problem using the NBO2 sensor heater power supply as a source for the LC-1 power in a vehicle where the heater is controlled by the PCM? Do you know whether the PCM does any PWM trickery or turns the heater off under certain conditions?

That's how I hooked mine up and I haven't noticed any loss of power during operation. The stock 12v source and ground should work just fine.

Thanks, have you checked a wiring diagram to see if the sensor heaters are controlled through the PCM on your car or if they're hooked directly to ignition voltage? My rears (gone now) are direct to the fuse box but the fronts are PCM controlled...

I believe this is what my setup looks like...
