Description

The Wabco 4492721000 is an ABS Connector Cable designed for use in trailer brake controls within air brake systems. This cable is an essential component of the Electronic Braking System (EBS), facilitating the connection between the trailer and the towing vehicle. It features a Connector ISO 7638 7-pin on one end and a Power 7-pin connector on the other, providing a reliable power supply line operating at ISO 24 V. Measuring 91 x 349 x 331 mm, this drawbar type cable adheres to OE specifications, ensuring compatibility and performance. The robust design and quality materials contribute to a secure and efficient braking system, enhancing safety and control.

Key Features & Benefits

This cable basically connects the wheel speed sensors on your trailer to the ABS control module. It’s a wiring harness, a bunch of wires bundled together with a connector on each end. Those sensors read how fast each wheel is turning and send that info back to the ABS module. It's a fairly simple part, but it does a critical job. Think of your trailer’s ABS system like a safety net. It prevents wheel lockup during braking, especially important when you’re hauling a load. This cable is how the system gets the information it needs to work properly. Without accurate speed readings from each wheel, the ABS can’t effectively modulate the brakes. It’s part of the communication network for the entire trailer braking system.

Symptoms, Risks & Replacements

If this cable gets damaged – corrosion, a broken wire, a loose connection – the ABS system won't get the right signals. You’ll likely notice if it’s completely broken, you might get an ABS warning light on your dash. But sometimes it’s subtle; maybe the ABS activates when it shouldn't, or doesn’t activate when it should. Either way, it compromises your braking safety. It acts like a shield, protecting against skids. We carry these at Fixparts Online, and it’s one of those parts where replacing it proactively is a good idea if you suspect any issues, especially if you do a lot of hauling or operate in harsh conditions.
