Magnaride level sensors

[B88i45]

I'm getting tried of canceling the service  suspension light so I want to get this figured out.  I have Bilstein shocks and struts on all for corners now, I also installed the resistors on all 4 corners where the magnarides were plugged in.  After about a year the light came back.  I replaced one resistor and tested/swapped the other three with new ones but I still have the light.  I'm thinking it's a level sensor now. Truck is a 2015 Denali.

 

Does anyone know if Shocksims still sells the 8 piece kit or is it just the OBD kit?  I have an email into them but hoping to get some more testing in this week.

 

Is there an app I can diagnose the suspension system with to see what the truck is reading?  Maybe do a relearn.  A GM version of AlphaOBD.

 

I have enough resistors to wire into the level sensors but I have not seen anyone say how to wire the three wires.  Anyone know where to get the info from?

 

 Level sensors are cheap enough but I just don't know which one it could be.  Anyway to test them?  Also, I don't particularly care for our dealerships here and getting them to do odd things like a relearn is like pulling teeth.
