Key Features & Benefits

This cable basically delivers the electrical signal from your truck’s brake pedal to the trailer’s brake system. It's how your truck tells the trailer to brake, sending power to the trailer's solenoids or electric brakes. It handles power and ground, and often a signal wire, allowing the trailer brake controller in your cab to adjust braking force. Some have multiple conductors for different functions – things like marker lights or reverse lights on the trailer might run through it too. Think of it as the main nerve connecting your truck’s braking intention to the trailer. It runs from the connector on your truck, usually in the bed, all the way to the electrical system on the trailer. It’s a critical link, really. Without it, pressing the brake pedal does…well, nothing to the trailer’s brakes. It's a relatively simple component, but essential.

Symptoms, Risks & Replacements

Without a good supply cable, your trailer brakes won’t work reliably, or at all. That’s a pretty big safety concern, obviously. A damaged cable can cause intermittent braking, where the trailer brakes work sometimes and don't others – incredibly dangerous. You’ll notice if the trailer starts to push you around when you slow down, or if you have to work much harder to control it. Corrosion is a big enemy of these, especially with road salt. If you’re having brake issues, it’s one of the first things to check. We carry a bunch of different styles and lengths, and you can find a good selection at Fixparts Online if you’re looking to browse. It's worth replacing it if there’s any doubt – a small price to pay for peace of mind.
