Who's installed an LC-1 wideband with ECU+ or DSMLink??

Well I have an LC-1 wideband setup & ECU+..I posted over in their forums like two weeks ago but nobody's answered, so figured maybe somebody here knows..

I'm just making sure I have everything right as far as hooking it up. I'm guessing you use the instructions from the LM-1?

Here's what I'm thinking...correct me if I'm wrong:
Connect the LC-1's Analog ground & System ground to pin 1 (labeled as Sensor Ground) on the ECU+ harness

Connect the LC-1's Heater ground to where you grounded the ECU+'s ground wire.

LC-1's Analog Output 1 goes to Pin 27 (Spare analog input 2/Wideband O2 sensor kit In) on the ECU+ harness.

But in the ECU+ manual, it says:

"A 3.5mm stereo connector provides the output that the ECU+ needs. Pin 1, the connector tip, is analog output 1. Connect this to the ECU+'s head unit."

So do I cut the stereo connector off & connect this to pin 27, instead of
the analog output wire???

Here's the pic from the LC-1's manual:

Also I'm a little confused on the order of getting everything setup..the ECU+ manual says to install the wideband first, calibrate it & everything, THEN connect the wires to the ECU+. Is this right?? Im guessing just calibrate the 02 sensor first, don't tune or anything..then hook the outputs to ECU+ & pretty much never have to use the LC-1 software again?

I was told to ground the system ground and the analog grounds to seperate grounds. Ground analog 1 and analog 2 to the same place, but ground the main ground somewhere else. I think that was my main problem.

Yeah I have that part figured out, the main thing that's confusing me is using the 3.5mm stereo connector..do I have to cut the stereo connector end off & use these wires, or do I use the analog output wire?
