The Grand Cherokee trailer wiring diagram consists of various components, including the trailer connector, wiring harness, and fuses. Let’s discuss each component in detail:

It is essential to ensure that the trailer connector is properly connected to the Grand Cherokee’s wiring system. A loose or improperly connected connector can cause the trailer lights to malfunction, or worse, it can cause damage to the vehicle’s electrical system.
Wiring Harness
The wiring harness is a set of wires that connect the trailer connector with the vehicle’s wiring system. The wiring harness consists of color-coded wires that correspond to specific functions, such as left turn, right turn, tail lights, brake lights, and ground. The wiring harness is specific to each vehicle model and is designed to ensure a secure connection between the vehicle and the trailer.
It is important to choose the right wiring harness for your Grand Cherokee. A mismatched or incompatible wiring harness can cause electrical problems and even lead to a short circuit.

The Grand Cherokee has two fuse boxes, one located in the engine compartment and the other in the passenger compartment.
