Trailer Wiring Harness Recommendation for 2018 Jeep Grand Cherokee without Trailer Wiring
Question:
So this can be installed similarly to the one I had on a 2011?? Some say you have to have your computer re-sequenced when installing on a model without the towing package. I never did that with my 2011 and it worked fine. Just wanting to make sure. Thanks

We do have a way you can install trailer wiring on your 2018 Jeep Grand Cherokee that does not have the factory tow package but the kit you mentioned is a tow bar wiring kit and is for vehicles that get towed behind a motorhome.
So what you'd need is the Tekonsha part # 118727 which plugs in line with the taillight connectors of the vehicle for a super easy install that does not require a reflash of the computer.
