Is the Mopar Flat-Tow Wiring Harness Required for a 2020 Jeep Grand Cherokee  


Hi , has Jeep done away with the need for the electronic power steering harness on the 2020 Grand Cherokee Limited. I know that this harness was a must so the Jeep wouldn’t go into the infamous “ death wobble”on earlier models. I have not been able to find anything on them now and the Jeep dealer says there is no kit for a Grand Cherokee. Also if not, does the Grand Cherokee Limited need a battery charging wire harness to keep the battery up while using a aux. tow brake unit

The Mopar Flat-Tow Wiring Harnesses are no longer required on newer Jeeps such as a 2020 Jeep Grand Cherokee. I have attached a list of parts that you will need to flat-tow said vehicle below. The battery charge line is not required.

etrailer Invisible Base Plate Kit part # e98950
etrailer SD Non-Binding Tow Bar part # e34ZR
Roadmaster Diode 7-Wire to 6-Wire Flexo-Coil Wiring Kit part # RM-15267
Blue Ox Patriot Braking System part # BLU37TR
