where is the lowside a/c line on this

when your hood is up. go to the left hand back corner. the low and hi are right b side each other. Theres a cap on each line {looks just like the cap on your tires} the line with the smaller adapter or inlet. is the low line {should be the line closest to the front of the car} or the line you put your refrigerant into. hopefully thats all it needs. good luck
