Not sure of those pins. That diagram is horrible! Download this manual here on your laptop and print out diagram on sheet of paper. There's absolutely zero way to trace wiring accurately on phone screen, unless you're able to draw on diagram, but that one is way, way too messy.
It's like what they say in maths class, "show your work". Let's see your "map", that is, the path you took from O2-sensor towards ECU connector. Let's be absolutely 100% positively sure about these pins, or else you're gonna fry ECU!!

New copy
How about this one I believe this is pin 5 b/g. And then pin 6 other side b/w
other two wires lead else where but I’m following the two from the resistor looking symbol. They originally are both white white then go into b/g and b/w.

Ok, awesome!!! Looks like you've identified ECU locations as
blk/grn #5 on blk connector and
blk/wht #6 on lg/gr connector
Now find those locations on each connector and look to see if there's a wire there. If not, is there at least female terminal in connector that touches ECU pin?
Also what value resistor are you using?

I’ll double check tonight but if memory serves me 5 was missing on black side. But had female connecter inside and 6 on gray did have wire. I believe that wire is shared to fuel cut off relay. And like other posts 330 ohm resistor

Alright just an update. I pinned those two with a resistor and sure enough engine light is now gone. I’m going to make it a very clean job when I get some time this weekend but just wanted to report back the news. Thx for your help

Well huge shout out to dannoxyz. For helping me out stayed with me literally entire time. I was laughing at one point because I was like this guy 100 percent knows exactly what pins and wires I need to use but wanted me to figure it out which is also really cool. Thanks again man. Teach me how to fish the old saying lol. Take care guys I’m sure I’ll be back on here soon

While I have you guys. Two more questions. Been reading about k and n filters. Bike has one currently. And people are saying need a power commander ,? I have a stock one should I go back to stock filter since I don’t have a power commander. And second air box is missing the ram air tubes on each side bike runs great but how important are those ? I can pick some up if it’s a huge need besides visual. Not working on new fairings as of yet so any advice on these topics much appreciated
