Standard Ignition RY-501 ABS Relay

ABS Relay for Porsche Brake Systems

Standard Ignition RY-501 is a 12-volt ABS relay built for Porsche brake system applications that require a 4-terminal, male blade, rectangular relay. With a 10-amp amperage rating and no continuous-duty design, it is specified for relay control in ABS-related circuits rather than constant-load operation.

Compatible With Porsche 928, Porsche 968, Porsche 911, and Porsche 944 applications across the listed model years, this relay supports direct replacement needs for ABS relay service. The Standard Ignition RY-501 is also cross-referenced to SKF 20643 for the same application.

• 10-amp amperage rating for specified circuit loads
• Rectangular connector shape for OE-style fitment
• 4 male blade terminals for direct relay connection
• No mounting bracket included

• No-start or no-activation conditions tied to relay control
• Heat- or age-related relay contact wear
• Replacement needs for Porsche ABS relay service

Installation Notes and Tips

Verify the connector shape, terminal count, terminal type, and amperage rating before installation. Confirm the vehicle application against the listed Porsche 928, 968, 911, or 944 fitment, and compare the original relay layout to Standard Ignition RY-501 before connecting. Because no mounting bracket is included, reuse the existing mounting arrangement if your vehicle uses one.
