If you own a 1999 Jeep Grand Cherokee and need to tow a trailer, you will need to wire your vehicle for trailer lights. Wiring your Jeep for trailer lights can be a daunting task, but with the right tools and some basic knowledge, you can get the job done in no time. In this article, we will provide you with a detailed guide on how to wire your 1999 Jeep Grand Cherokee for trailer lights.
Tools Needed:
Before you begin, it’s important to gather all the tools you will need. Here’s a list of tools you’ll need for this project:
| Tools | Description |
|---|---|
| Wire strippers | A tool used to remove the insulation from the end of a wire. |
| Wire crimpers | A tool used to attach connectors to the end of a wire. |
| Multimeter | A tool used to measure the electrical properties of a circuit. |
| Electrical tape | A type of tape used to insulate electrical connections. |
| Wire connectors | Connectors used to attach wires to each other. |
Step-by-Step Guide:
Step 1: Locate the Tail Light Wiring Harness
The first step is to locate the tail light wiring harness. This can be found behind the driver’s side kick panel. Once you locate the wiring harness, you will need to untangle it from the other wires to access the wires you need for the trailer lights.
Step 2: Identify the Wires
The next step is to identify the wires you will need for the trailer lights. You will need to look for the following colors:
| Wire Color | Function |
|---|---|
| White | Ground |
| Brown | Tail lights |
| Yellow | Left turn signal |
| Green | Right turn signal |
Step 3: Splice into the Wires
Once you have identified the wires you need for the trailer lights, you will need to splice into them. To do this, you will need to use wire strippers to remove a small section of insulation from each wire. Next, you will need to use wire crimpers to attach the connectors to the ends of the trailer wires. Make sure that the connectors are securely attached and that there is no exposed wire.
Step 4: Test the Connections
Once you have attached the trailer wires to the Jeep’s wiring harness, you will need to test the connections to make sure they are working properly. To do this, you will need to use a multimeter to check the voltage at the connectors. If there is voltage, then the connections are working properly.
Step 5: Secure the Wires
Once you have tested the connections, you will need to secure the wires to prevent them from getting damaged while driving. You can use electrical tape to secure the wires to the Jeep’s wiring harness.
