SetAmbientColor() in TGE 1.5

Hi,

I'm trying to use Enviro-Torque resource (http://www.garagegames.com/index.php?sec=mg&mod=resource&page=view&qid=8848) in TGE 1.5. Its Celestials class calls setAmbientColor in the light manager object. This method don't exists in TGE 1.5 (it sounds like tge 1.5 have a new light manager system).
Celestial class also calls setVectorLightsEnabled and getLight(0) that also dont exists in TGE 1.5 LightManager object (see below):

/**  Heavens::UpdateSunPosition() does just that. 
       It updates the position of the sun.  
       The fxSunLight class must be updated to 
       grab elevation and azimuth data from  this 
       class object.*/
void Celestials::UpdateSunPosition()
{    

...   
//***************************    
// Now do the lighting stuff    
//***************************    
   GetColor(mCurrentColor);    
   LightManager *lm = gClientSceneGraph->getLightManager();    
   lm->setVectorLightsEnabled(false);    
   lm->setAmbientColor(mCurrentColor);
}

...

Sun* Celestials::GetSunObject()
{    
    return (Sun*) &(gClientSceneGraph->getLightManager()->getLight(0));
}

...

Someone can help-me to convert this code to TGE 1.5?
Sorry for bad english and thank u!
