Trailer Wiring Harness Recommendations for a 2020 Jeep Grand Cherokee Laredo


I need the wiring harness for 2020 Jeep Grand Cherokee Loredo


Expert Reply:

The correct wiring harness for your 2020 Jeep Grand Cherokee Laredo depends on whether or not you have the factory tow package:

With Factory Tow Package - # 118384
Without Factory Tow Package - # 118727

The one for the tow package plugs into the factory connector at the back while the one for the non-factory tow package tees in behind your tail lights and is powered directly from your battery by the included wiring lead.

Theses are the 4-Way harnesses for basic trailer lighting. If you need a 7-Way then you need the following:

With Factory Tow Package - # HM40975
Without Factory Tow Package - # ETBC7 (in addition to the # 118727)

I also recommend picking up the No-Drill Mount Bracket # 18140 which allows you to mount the wiring connector near your hitch receiver. The 7-Way wiring kits come with brackets to fit to the No-Drill Mount but if you're using a 4-Way you also need the Bracket # 18144.

Attached are some videos for you to check out as well!
