Here's a breakdown of what you might find:
* ABS Wheel Speed Sensors: These sensors are crucial for the ABS system's operation. They detect the rotation speed of each wheel, allowing the ABS to modulate braking pressure and prevent wheel lockup during hard braking. These are the most likely connection you'll find in the rear wheel cradle.
* ABS Tone Ring: The wheel speed sensor doesn't directly contact the wheel. Instead, it reads a "tone ring" – a toothed metal ring attached to the wheel hub or axle. The sensor detects the changes in magnetic field caused by the rotating teeth, translating this into a wheel speed signal. You won't directly see this electrical connection, but it's important to know this is part of the system.
It's *unlikely* you'll find separate connections for the vehicle speed sensor (used for speedometer and cruise control) in the rear wheel cradle on this model. Those sensors are usually located elsewhere in the drivetrain, such as the transmission or differential.
To confirm:
1. Visual Inspection: Carefully examine the wiring harness entering the wheel cradle. Look for connectors that are the right size and type for speed sensors (they're usually relatively small, and may have a shielding).
2. Wiring Diagram: Consult a 1994 Chevrolet Beretta wiring diagram. These diagrams show the exact location and function of each wire and connector. A Haynes or Chilton repair manual for your car would contain this. Online resources like AllDataDIY (subscription required) are also helpful.
3. Trace the Wires: If you can safely follow the wires from the connectors in the wheel cradle, you should be able to see where they go (ABS module, etc.).
Caution: Be careful when working near the rear wheel cradle. Disconnect the battery's negative terminal before working on any electrical components to avoid short circuits.
