Hello All,
Hoping to get some advice.

My A/C compressor was not clicking on; I was able to source it to the pressure switch. The connector had some blue gunk all over it, so I changed both the connector and the switch. The new switch still didn't allow voltage through; so I jumped the connector to try and charge the system thinking once the system had some refrigerant the switch would work.

Leading to my current issue; the system is not taking a charge from the lo-side to the hi-side even when the A/C clutch is engaged. Maybe I need a new dryer or orifice tuber but would either of these stop the hi-side from charging?
*The system held a vacuum for over an hour and the vacuum was run for another hour prior to me trying to charge the system. (Reading was roughly -30 before adding r134)
*Then I added r134 to the hose; purged any air in the r134 line and opened the lo-side. (Not sure what measurement to read, but the lo-side gauge needle jumped to around the middle)
*The hi-side gauge did nothing.

A little back story:
*In October of 2018, I finished installing a rebuilt 4.0 along with all new A/C components, so I could run r134a clean-the system was previously run using r12.
*Since I was running on a newly rebuilt engine I hooked the A/C system up but left the power to the clutch unplugged.
*I did not pressurize the A/C system I just started the new engine and broke it in without doing anything to the A/C system; that was close to 8 months ago.

Any advice would really be appreciated?

Diagnose the problem! Don't make a wish and throw parts at it like I use too.

If you aren't getting a pressure reading on the high side, then your gauge is bad. Even if the orifice and drier are clogged, there should always be static pressure at the high side Schrader valve.
