Has anyone ever found where this is located on a 2016 1500? I never knew it even existed.

If you’re picturing a black box like an airplane that’s not how it works. Most modules are able to record data when certain events happen like a dtc or an accident.

most event data recorders are in the seat belt module. Deploying the airbags is not a requirement to make the recorder lock the data. Have you ever seen the data from the recorder?

Is there away to disable this.

I think this is what you're looking for:
The Occupant Restraint Controller (ORC) (1) is located in the passenger compartment of the vehicle, where it is secured by three nuts to two studs of a stamped steel adapter bracket and one stud of the mount welded onto the top of the floor panel transmission tunnel under the center front seat section or the center floor console, as the vehicle is equipped. Concealed within a hollow in the center of the molded plastic ORC housing is the electronic circuitry of the ORC which includes a microcontroller, an electronic impact sensor, an electronic safing sensor, a integral Electronic Stability Control (ESC) dynamics sensor (also known as the yaw sensor or sensor cluster) and a energy storage capacitor. In 1500 and 2500 models, the ORC also includes an internal rollover sensor. A stamped metal cover plate (3) is secured to the bottom of the ORC housing with screws to enclose and protect the internal electronic circuitry and components.
An arrow printed on a label on the top of the ORC housing provides a visual verification of the proper orientation of the unit, and should always be pointed toward the front of the vehicle. The stamped metal cover plate of the ORC has integral flanges with three mounting holes (2). A molded plastic electrical connector with two receptacles (4), each containing numerous terminal pins, exits the right facing side of the ORC housing. These terminal pins connect the ORC to the vehicle electrical system through dedicated take outs and connectors of both the instrument panel and the body wire harnesses.
A molded plastic protective cover is installed over the ORC to provide additional moisture contamination protection to the unit. Integral latch features on each side of the cover engage slots at the front and rear of the adapter bracket beneath the base of the ORC housing to secure the cover over the ORC. This protective cover must be reinstalled following any service requiring its removal.
The impact sensor and safing sensor internal to the ORC are calibrated for the specific vehicle, and are only serviced as a unit with the ORC. The ORC cannot be repaired or adjusted and, if damaged or ineffective, it must be replaced.
The ORC microcontroller continuously monitors all of the SRS electrical circuits to determine the system readiness. If the ORC detects a monitored system fault, it sets an active and stored Diagnostic Trouble Code (DTC) and sends electronic messages to the IC over the CAN data bus to turn On the airbag indicator. An active fault only remains for the duration of the fault, or in some cases for the duration of the current ignition cycle, while a stored fault causes a DTC to be stored in memory by the ORC. For some DTCs, if a fault does not recur for a number of ignition cycles, the ORC will automatically erase the stored DTC. For other internal faults, the stored DTC is latched forever.
The hard wired inputs and outputs for the ORC may be diagnosed using conventional diagnostic tools and procedures. Refer to the appropriate wiring information. However, conventional diagnostic methods will not prove conclusive in the diagnosis of the ORC or the electronic controls and communication between other modules and devices that provide some features of the SRS. The most reliable, efficient and accurate means to diagnose the ORC or the electronic controls and communication related to SRS operation requires the use of a diagnostic scan tool and may also require the use of the SRS Load Tool special tool along with the appropriate Load Tool Jumpers and Adapters. Refer to the appropriate diagnostic information.
