I have a 94 Integra LS Hatchback
My ac needs a recharge probably, and I know you need to use the low-side port and not the high-side

Usually each one has a cap on it; one is marked H (high) and another is marked L (low)

Unfortunately, both caps are missing on my car, so I don't know which one is supposed to be L

I was hoping someone could send me a photo of under the hood and then on it label where the low-side is for me
