Curt has a brake controller install harness that fits your 2023 Jeep Grand Cherokee L with the part # C51446 which you could use with a Curt brake controller like the Triflex part # C51140. To find the connector in your vehicle you'll need to drop the lower dash panel and then look for the gray connector behind the PCM near where the e-brake pedal is.

There is no e-brake pedal on my 2023 Grand Cherokee Overland.

@TomG I would still look in that general area. The manufacturers of the harnesses are so used to using the e-brake pedal as a reference point most likely they just left that in there.

In my daughter’s 2024 Grand Cherokee L, it’s on the driver side under the kick panel hatch where the electric parking brake manual release and fuses are. It’s tucked up and behind them taped to the wiring harness.
