92 LS400. Just want someone to confirm that the A/C service valve (low pressure, suction) is located just above bumper, just behind hood grill. Thanks

How and where do I add refrigferent on 92 LS400 ? I used to do it with a kit on previously owned cars, but never worked under the hood of my 92 LS400, and am therefore unfamiliar with location of parts. Thanks !
