Ranger support

[Pug_Commander]

Hey, I have a 2014 Ranger 900 XP. I see only 2015+ is supported. I have compared both wiring diagrams from a 2014 and 2015 and there are no differences other than the 2015 has a seatbelt wired into the ECM. Is there another reason I'm not seeing as to why the 2014 is not supported. A follow up question if I find out the 2014 is supported I would like to wire in an O2 sensor and was wondering if anybody knew the pinout on the ECM where I could add it? I'm new to this so trying to drink from a fire hose at this point, thanks for any and all input.

I just started a support ticket for a 2013 ranger 900. I feel like a 13 or 14 should be pretty much the same as the 15 up.
the 13 has the ME17.9.74 controller.
Mine will read the calibration and then give me the "validate checksum failed" error

I did notice there's a difference in 13 to 14 with where the diag port connects to regarding the ecm. The 14 is identical to the 15, except for the seat belt connected to pin 225 or 125. I can't remember the specific side but that is really the only difference. The 13 and 14 have different spots where the power splices in through the diagnostic port though so I feel like that is the difference in their support for the 14 possibly thinking they are the same?
