Here's a general overview of the installation process:
1. Choosing a Mounting Location:
* Select a location for the controller within easy reach of the driver but out of the way of other controls and obstructions. The dash or center console are common spots.
* Ensure the location allows sufficient wiring access to the battery and the brake light wiring harness.
2. Running the Wiring:
* Power Wire: This typically requires a connection to the battery's positive (+) terminal. This often involves running a heavy-gauge wire from the controller to the battery, using appropriate fuse protection (as specified by the controller's instructions). This is crucial to prevent overheating and potential fires. You may need to drill a hole in your firewall or find an existing grommet to route the wire through.
* Ground Wire: Connect the ground wire from the controller to a clean, unpainted metal surface on the vehicle's chassis. A good ground is essential for proper operation.
* Brake Light Wire: This is the most important connection. You'll need to tap into the brake light wire in the vehicle's wiring harness. This wire provides the signal to activate the brake controller. Locating this wire is critical and often involves some careful investigation. You'll need to use a wiring diagram specific to your 1998 Chevy pickup to identify the correct wire, and usually a test light or multimeter is needed to confirm. Some controllers may have a built in wire that splices into the stop lamp wire. Improperly connecting this wire can damage the controller or vehicle electrical system.
* Towing Wire: The controller has a wire designed to connect to the trailer's brakes. You'll route this wire to the hitch connector.
3. Making the Connections:
* Use appropriate connectors, crimps, and heat shrink tubing to ensure secure and waterproof connections. Poor connections can lead to corrosion, intermittent operation, or even failure.
* Use a multimeter to confirm wire continuity and voltage after making all connections to avoid damaging your truck and ensure the controller is properly installed. Doing this can save you hours of troubleshooting and potential damage.
4. Mounting the Controller:
* Securely mount the controller in the chosen location using the provided hardware.
5. Testing:
* Once installed, test the controller thoroughly. Connect a trailer with properly working brakes. Apply the brakes slowly and gently, and increase pressure gradually. Check for proper brake activation on the trailer. Observe the indicator lights on the controller.
Important Considerations:
* Wiring Diagrams: Obtain a wiring diagram specific to your 1998 Chevy pickup. This will be invaluable in identifying the correct brake light wire. You can usually find these online through forums or repair manuals.
* Fuse Protection: Always use the correct fuses specified by the brake controller manufacturer. Insufficient fuse protection can lead to electrical fires.
* Professional Installation: If you are not comfortable with electrical wiring or automotive repair, consider having a professional install the brake controller. Incorrect installation can be dangerous and void warranties.
* Trailer Wiring: Ensure your trailer's wiring is properly connected and functioning correctly.
This is a simplified explanation. The exact procedure will depend on the specific brake controller you choose and the year and model of your Chevy pickup. Always refer to the brake controller's installation instructions and your vehicle's wiring diagram for detailed, model-specific information. Remember safety is paramount. If you're unsure about any step, seek professional help.
