Default 87 CRX HF A/C quiestion

Well, it's been awhile since I last posted. I've been working on the old CRX and it's running pretty well now.

Issues overcome. When I'd hit a bump quite often one of the rear brakes
(take your pick) would lock up. Solved it by buying a new set of springs
and installing as the originals were just so fatigued. I also pulled down the hydraulic cylinders and honed them out, cleaned them up and reinstalled and bled the system so it now has new brake fluid through out.

Emergency brake issue was one side would stick and drag costing fuel mileage. So I got an assistant and pulled that side down and pumped lube
into the cable and held the lever end with a vice grip plires while assistant
held rear brake shoe and we pulled it back and forth to migrate the lube into
the cable housing. This also required removing the console, as it's much easier to do this without the console in place.

Ignition timing is now correct so that I've gotten 60 mpg on trips. Last trip was on hilly terrain in southern Ohio and partly flat land 4 lane and I averaged 58.7 mpg.

Presently I'm having A/C issues. This was Dealer Installed Honda A/C.

I think the low pressure switch may be sticking. The A/C works quite well
but it will eventually quitis for awhile. Usually if I stop the car and let it sit
where the pressures on the high and low equalize it may come back on.

What I'd like to do is locate that switch. The High Pressure switch is up on top by the sight glass but I'm not sure where the Low Pressure switch is.

Does anyone here know ? I'll take it loose and jumper it together just to test and see if that's the problem. Thinking I'll run some wires into the car
so I can cycle it with a toggle switch. Then if it works like it should I'll know to get a low pressure switch and replace it.

So, where's the Low pressure Switch ?

Thanks.
