Question:
I have 2018 Jeep Grand Cherokee Altitude. I do not believe it has the factor tow package, but I do see the grey 4 pin connector for brake controller above the emergency brake. Should the jeep have the trailer lights and brakes wiring ran to the back if it has this 4 pin connector? I checked to see if the plug was tucked above the rear number but I did not see it.

Expert Reply:
The first thing you need would be a 4-way installed on your 2018 Jeep Grand Cherokee which for that the Tekonsha kit part # 118727 is the easiest to install and has the most reliable converter box. Since you said you need brakes too you'll have to install a brake controller like our very popular and reliable Prodigy P2 part # 90885. To install this the kit you'd want is the # ETBC7 which comes with everything needed to convert the 4-way to a 7-way and wire in a brake controller.
The P2 uses an inertia sensor to determine how hard you are applying the vehicle brakes and apply a similar amount of braking pressure on the trailer brakes.
