LP cutout switch
Forgive me, I'm flying blind until my Haynes manual arrives and then I'm not even sure that'll help. This a 2001 F-150 XLT 4x4.
The other day, the manual A/C went from cold to hot in a heartbeat. I'm trying to do the simple things first like jump the LP switch and see if it works. Now I learned there is no LP switch on the truck so I can't try that.
Next, I figured I'd put my A/C gauges across the hi and low ports and see what is happening but I can't do that because now I learned I need "port adapters". I searched the web and found about 20 different ones to pick from. Does anyone have a source and a part # for these adapters?
Is black death a common problem with these trucks?

There is a low pressure cycling switch mounted on the top of the accumulator.
Adapters are only needed if your manifold gauge set was made for use with some other refrigerant system (other than R134a). If it's an older gauge set meant for automotive R12 systems, those adapters are easy to find. Google "r12 r134a gauge adapter"
