So, I currently have this code from 1.8:
public static void drawBoundingBox(AxisAlignedBB axisalignedbb)
{
Tessellator tessellator = Tessellator.getInstance();
tessellator.startDrawingQuads();
tessellator.addVertex(axisalignedbb.minX, axisalignedbb.minY, axisalignedbb.minZ);
tessellator.addVertex(axisalignedbb.minX, axisalignedbb.maxY, axisalignedbb.minZ);
tessellator.addVertex(axisalignedbb.maxX, axisalignedbb.minY, axisalignedbb.minZ);
