Could someone help me to wire up the Innovate LC-1 to a 2004 V11 RC please.

It has the wiring loom for the ‘with catalyser’ version and has a 4 pin plug which connects to the standard O2 sensor.  The sensor connects to the My15M via the main connector, I am not using the 3 pins on the pcb.  The My15M reads this O2 sensor OK and runs closed loop using voltage settings as suggested by Cliff.
I would now like to use a wideband system my intention is to cut the wire off an old standard O2 sensor and wire it to the LC1 so that I can plug it back into the bike loom rather than run extra wires to the pcb pins.
This much I know. Grounding is very important. LC-1 must be supplied with 12v as soon as the ignition is switched on to allow the O2 sensor to heat up to avoid any thermal shock to the 02 sensor, this is supplied by the 4 pin plug from the injection power[size=12][/size] relay.  I will also have to edit my map back to the original LC-1 voltages.

My problem is with the analogue inputs to the 4 pin plug.

As standard the bike is wired as below:

Original 02 sensor                        4 pin socket      
                 
Pin 1 black        Heater ground      Pin 1 Black               Ground
Pin 2 grey         Heater 12v           Pin 2 Red/Black        +12v from injection relay                                                            
Pin 3 White       Analogue ???        Pin 3 Orange             ECU pin 8
Pin 4 White       Analogue ???        Pin 4 Orange/Black    ECU pin 2


I intend to add the LC-1:

Innovate LC-1                             4 pin socket      
                 
Red         12v supply                   Pin 2 Red/Black     +12v
Yellow       Analogue Out 1           ????                     ????
Green       Analogue Ground                                    Common ground
Blue         Heater Ground                                        Common ground
White       System Ground                                       Common ground
Brown      Analogue Out 2                                       AFR Gauge
Black       Calibration wire                                       Calibration switch

Which pin of the 4 pin plug should the yellow wire go?

ECU pin 2 is ground.

I find the stock sensor on my Breva 750 works quite well. They're not as bad as the earlier narrowband sensors and seem to have a medium band response.

So have I been wasting my time following the previous advice generally in the forum about fitting LC-1?

The LC1 is recommended for those who do not have a sensor to start with. I don't recall it being advised that you should replace the OEM sensor with one.
Can you point me to where that was said. I had a look at you last 25 posts to Oct and there is no mention about the LC1.

My bike did not have an 02 sensor as standard. I do recall you recommending an LC-1 at that point.

Since then I have obtained a second hand crossover with sensor and have been running closed loop with the oem sensor using the AFR voltages you kindly supplied from,. I believe, the V1100 Breva.

I then got a used LC-1 which drives an analogue AFR gauge.

I was hoping to now move onto using the wideband sensor/LC-1  with the My15M but am unsure which wire from the LC-1 should go to the 4 pin plug and so to the ECU.

I think I have worked it out now. My15M pin 8 is the input for the O2 sensor, pin 2 being a ground as far as I can tell.  So I will connect my LC-1 Analogue Out 1 to pin 3 of the 4 pin connector which should then run through to pin 8 of the ECU.

I had raised this as another post some time ago but it wandered off thread a little but rereading it prompted me to have a good look at the pcb.

Thanks anyways.
