The switch is mounted on the liquid tank out on the condenser. I am sending a diagram to help you locate the switch.

The condenser is in front of the radiator, the close up is showing you the condenser, I would probably try removing the grill to get decent access to it.
Sorry, the radiator is in the engine compartment
So is the condenser,
and YES, i DID ANSWER YOUR QUESTION, YOU HAVE A DIAGRAM OF THE PRESSURE SWITCH IN YOUR POSSESSION.
I opened the link without a problem.
Here it is again. If you still can't get it, please let me know as the site may have an issue.
I am TRYING to help you. I can only type so fasst
Sorry, I can't do phone calls.
Is that a question or a statement?
Sure, you can run a power wire directly to the wiring harness and the clutch will kick on.
This is a very complicated system. The pressure switch is the only pressure switch on the system, it does both high and low pressure. Either will prevent the clutch from coming on.
If the condenser fan isn't working then the pressure will be to high and the clutch won't come on. If there isn't enough freon in the system then the clutch won't come on due to low pressure.
If the intake temp sensor inside isn't working then the compressor won't come on when it has the auto air system. If the ambient air temp sensor isn't working, then the compressor won't come on.
As you can see it's pretty complicated. If you don't know how much freon is in the system then that is probably the place to start.
We are not looking for coolant, we are looking for freon.
If it's low, then the compressor isn't going to come on.
Intake sensor is inside the cabin where the little vent is next to the steering wheel ambient is out at the bottom of the condenser to the passenger side under the bumper.
After all your threats, this is as far as I am willing to go with you on this.
If you would like I will be happy to open it up to the other experts, but I think it's fairly saf to say no one else will reply.
According to the wiring diagram the sensor stays in a neutral state until the pressure is to high or to low, then it sends a signal to cut the a/c via the communication lines and the IPDM. Jumping this isn't going to help.
Not sure how you can check the pressure without the clutch running.
usually we adjust the freon with weight, not pressure.
Have yo added any?
How exactly have you checked for leaks?
