Wabco 8946073900 Wiring Harness

Description

This Wabco wiring harness (MPN: 8946073900) is a critical component within the ABS sensor system of drivetrain electronics. It’s designed for use in connecting various ABS components, ensuring reliable communication and functionality. This harness features a 7-pin bayonet socket on one end and a 7-pin plug with a blue cap for display and diagnosis, alongside an open 5-strand cable. Measuring 63 x 324 x 364 mm, this OE specification harness offers a robust and precise connection, maximizing signal integrity and system performance. Its durable construction and accurate design contribute to extended component life and reduced maintenance needs.

Key Features & Benefits

This harness is basically the network of wires that connects your ABS wheel speed sensors up to the ABS module – that’s the brain of the system. It carries the signals from each wheel sensor – telling the module how fast each wheel is spinning – and also delivers power to those sensors. It’s not just a single wire, it’s a whole assembly, often with multiple connections and protective coverings. The ABS system relies on knowing how fast each wheel is turning. If one wheel starts to slow down dramatically compared to the others – like during hard braking or on a slippery surface – the ABS module uses that info to prevent wheel lockup. The wiring harness is the messenger delivering that critical speed information. It’s how the system “sees” what the wheels are doing. It’s part of the drivetrain electronics, specifically focused on letting the ABS system function.

Symptoms, Risks & Replacements

Well, if this harness gets damaged – frayed wires, broken connectors, corrosion – that signal gets interrupted. You’ll notice if the ABS light comes on, that's usually the first sign. Sometimes you might not get a light right away, but the system simply won’t work when you need it. Essentially, a bad harness can disable your ABS, making your stopping distances longer and reducing your control, especially in bad weather. It acts like a shield for the signals, and if that shield is compromised, the system can't function reliably. You can find a replacement pretty easily – we stock a good range here, and you’ll also see them online at places like Fixparts Online. It’s one of those things that's easy to overlook until it causes a bigger problem.
