However, the most common places to find the trailer brake wire (often a blue wire, but color can vary) include:
* The 7-way RV connector: If your truck has a 7-way RV-style trailer connector, the trailer brake wire is usually one of the wires within this connector. You'll need a wiring diagram specific to your truck's year and model to identify the correct wire.
* The 4-way flat connector: Less commonly, the brake wire might be in a 4-way flat connector. Again, a wiring diagram is crucial to determine its location.
* Near the taillights: The brake wire may be tapped into the taillight wiring harness. This is less common with factory installations, but more common with aftermarket installations.
* Under the dash: In some rare cases, the wire might be routed and connected under the dashboard, usually near the fuse box or other related electrical components.
To find the wire accurately:
1. Consult your owner's manual: It *might* have a wiring diagram showing the trailer connector wiring.
2. Obtain a wiring diagram: A wiring diagram specific to your 2000 Silverado's year, make, model, and trim level is essential. You can usually find these online through auto parts websites or repair manuals. Make sure you are using a diagram that's correct for your specific vehicle's configuration.
3. Use a multimeter: If you have some electrical knowledge, you can use a multimeter to test the wires in the connectors or harness to identify the brake wire. Be extremely cautious when working with electrical systems.
Without a wiring diagram specific to your truck, pinpointing the exact location is difficult and potentially dangerous. Incorrect wiring can damage your truck's electrical system. If you're not comfortable working with vehicle wiring, it's best to have a qualified mechanic locate and install the wiring for your trailer brakes.
