For the correct plug-and-play wiring harness to go with the Curt Spectrum Trailer Brake Controller # C51170 on your 2018 Jeep Grand Cherokee with a 7-way and tow package, that is the Curt Custom Wiring Adapter for Trailer Brake Controllers # C51446. With this adapter, you will be able to simply plug in the Spectrum wiring right into the port under your dash for easy installation.
