Key Features & Benefits

This cable is pretty straightforward. It simply delivers electrical power to your trailer brake control. It's a short, 0.3 – meter length, so it's designed to connect the brake controller itself to the vehicle's power source – usually somewhere behind the dash. It’s got the right connectors on both ends to plug in easily, and it’s built to handle the amps needed for a trailer braking system. Think of it like the veins in your body, delivering what's needed to make things work. In this case, it’s delivering electricity specifically to the part that lets you control your trailer’s brakes from inside the cab of your truck. Without this, the controller isn’t getting any juice and can't activate the brakes on the trailer when you hit the pedal. It’s a crucial link in the braking system.

Symptoms, Risks & Replacements

Well, your trailer brakes are really important, obviously. They handle a huge part of the stopping power when you're towing. If this cable is damaged – maybe it's frayed, corroded, or a connector is broken – you’ll notice if your brake controller isn’t working right. It might be intermittent, or just completely dead. A faulty cable essentially cuts off communication and power to the trailer brakes, and that's a safety issue. It acts like a shield protecting the whole system. You can find these pretty readily, Fixparts Online has a good selection if you’re looking, and replacing it is usually a fairly simple job if you’re comfortable with basic electrical work.
