location of the low pressure switch for the AC unit???

[Delicanadabc]

Hey

I am looking to find the location of the low pressure switch. Please email or post your reply.
We bypassed the clutch and got the temp down to 7.6 C. We tried to add more gas but there seems to be plenty of pressure as it doesn't seem that any more gas is getting in(hopefully not over full...)

Is there a separate fuse for the AC unit as there is none indicated on my fuse diagram?



Thank you,
Daniel
