During the removal of my radiator I trashed this sensor.
Can someone please tell me what this is named, I'm hoping to be able to pick one up tonight at a parts store.
It is below the radiator cap and attached to metal tubing.

Your not gonna be able to change that without having the system emptied.
So a/c system was emptied at a shop a few weeks ago when I replaced the heater core.

Just picked up an a/c switch at AutoZone but it's not matching up :(

Here's a link to what I picked up. Any help on what I'm actually looking for would be greatly appreciated, thanks!

You can drive as it is just a pressure switch for the A/C. No A/C till you replace it and recharge the system though!
Ok, thanks, wanted to make sure that sensor didn't also operate the cooling fan...
I'm assuming this isn't a sensor I can pick up at a local AutoZone/O'Reilly/advanced auto??
Thanks again for all the help guys! 👍

If it is a 4.0 motor and probably others are same. The Service Manual says the A/C High Pressure Switch connection on the pipe has a Schrader Valve and the switch can be changed without discharging the A/C system.

Below is what the manual says:

A/C HIGH PRESSURE SWITCH
DESCRIPTION

The a/c high pressure switch is located in the discharge
line near the condenser. The switch is
screwed onto a fitting that contains a Schrader-type
valve, which allows the switch to be serviced without
discharging the refrigerant system. The discharge
line fitting is equipped with an O-ring to seal the
switch connection.

REMOVAL
(1) Disconnect and isolate the battery negative
cable.
(2) Unplug the wire harness connector from the
high pressure switch, which is mounted to a fitting
on the discharge line near the condenser inlet.
(3) Unscrew the high pressure switch from the discharge
line fitting.
(4) Remove the high pressure switch from the
vehicle.
(5) Remove the O-ring seal from the discharge line
fitting and discard

INSTALLATION
(1) Lubricate a new O-ring seal with clean refrigerant
oil and install it on the discharge line fitting.
Use only the specified O-rings as they are made of a
special material for the R-134a system. Use only
refrigerant oil of the type recommended for the compressor
in the vehicle.
(2) Install and tighten the high pressure switch on
the discharge line fitting. The switch should be handtightened
onto the line fitting.
(3) Plug the wire harness connector into the high
pressure switch.
(4) Connect the battery negative cable.

It does have the schraeder valve so loss of charge is minimal if done right.
