2.3L ('83-'97) 93 ranger ac issue

Sounds like you've got a solid handle on the process. But, if I understand you correctly, you tapped the high pressure cutoff into clutch power? It wants to be in series, so clutch power cut and each leg of the switch pigtail attached to one side of the wire.

Stock, clutch power goes through the low pressure switch, then high pressure switch, then WOT relay. The exact order of the 3 components shouldn't matter, but you do want them all to be before the diode, so make sure you're not grabbing the wire between the diode and the clutch.

Completed the job at 65 degrees F … low side psi at 30 and high side psi at 170 I’m going to wait till noon tomorrow and see if the pressures stay normal when it heats up

Update so at 80f my low side is at 40psi but high side at 300 at idle after leaving truck on for a hour when I rev the engine the low side drops to 200 should I get a extra fan or will the ac system work fine with that high psi for the high side

Since you replaced the entire system, aren't over on oil, and low-side pressure is good, if the A/C works the whole time and high-side drops to 200 when you spin up the fan, I'd personally make sure I'm not missing anything obvious about my cooling situation and send it.

Since you had A/C stock, I assume you already have condenser seals and a fan shroud with the fan positioned in it properly. You also said you already have an aux fan. If that's in front of the condenser pushing (and it's actually coming on) there's not a ton more you can do.
