Back in the cool air again
Thought I was going to need to added freon and vac the system, but hey it had a shrader valve in it, took a minute or two to figure out the wires. Used an Ohm meter to see which group was which and now we are back in cool air again!

It seems to work
It's fit. And was easy to adapt to the wiring harness by soldering into the old connector. Seems to be a little bit difficult to tighten.

Amzn left out one critical dimension
"Frequently returned item."The reason for that is that is that the amzn Product Description omitted the ONLY critical dimension. The diameter and threads of the mounting hole. CRITICAL! The condenser ports are not all the same.This is an aftermarket item, used more on customizing cars rather than OEM replacement.The pressure cutoff specs would have been helpful too.It didn't fit mine. I don't even know if it works.And I'm past the return window because of interruptions beyond my control.So I have a new, unused, probably perfectly good part I can't even pass along to someone else!

doesn't work with a relay fan setup. It will kick the fans on multiple rides Minute
works well. Please note. This switch trinary finction will kick your electric fans on when high pressure reaches over 250psi. If you try to run this switch to a relay to kick your fans on, your fans will set there and kick on and off as the pressure gos above and below 250 psiI ended up just using the binary function of the switches a safety switch.

Wiring
Fit port fine. Doesn't switch with the compressor. Wiring not the same as YouTube vids. If I figure it out I will update and raise rating. Added to 87 Blazer. Fit port.

Works great!!
Works with 1977 Corvette but to be used on high pressure rail, it will require an adapter. It is too big for the r-12 mail port. Old air products sells the female to female adapter.

Works for 1994 Motorhome
One thing about working on old Rig is that alot of original parts are discountinued including my a/c's trinary switch. Luckily, this item here works like a charm. There was no wiring diagram and I dont know how to hook this up. But youtube is your friend for hooking it up. It's so easy. I was so tress for nothing!
