Question:

I need to add a trailer tow harness to my 2018 Grand Cherokee Limited. The jeep didnt originally come with a tow package and I cannot find where to plug into the wiring. Any help with parts and location would be great

Hello Eric, thanks for reaching out. The 2018 Jeep Grand Cherokee Limited without the factory tow package will use the Curt T-Connector # C62VR. This will plug in behind the taillights on the driver and passenger side and it provides a 4-flat trailer connector. I have provided a link to our install video for you below. Fast forward to about the 3:00 mark and you can see Ryan remove the taillight housing revealing the plug in location for the T-Connector.

Hey Eric, how did things go with the Curt T-Connector on your Grand Cherokee? Did the plug-in points behind the taillights match what you saw in the video? Your update could make it easier for others adding wiring to a Jeep without a tow package.
