Standard Ignition RY-790 Computer Control Relay

Computer Control Relay for OE-Style Electrical Repair

Standard Ignition RY-790 is a 12-volt computer control relay built for demanding underhood electrical systems. It uses a square connector shape, 4 male blade terminals, and a 70 amp amperage rating to support relay-controlled circuits in a wide range of Ford, Lincoln, Mercury, Chevrolet, Buick, Cadillac, and GMC applications.

Built with composite housing materials and specified brass or copper contacts where required, this relay is made for heat exposure and long-term electrical wear resistance. Standard Ignition RY-790 is a direct-fit style replacement for vehicles that call for a square, 4-terminal relay layout.

Key Features

• 12-volt computer control relay
• 70 amp amperage rating for higher-load circuits
• Square connector shape with 4 male blade terminals
• Composite housing for harsh underhood conditions
• Brass or copper contacts where specified for extended wear
• Manufactured under TS16949 and ISO9001 certified processes

Detailed Description

Standard Ignition RY-790 is engineered for electrical systems that rely on relay switching for computer-controlled operation. It is commonly used in applications such as the Ford Fusion, Ford Explorer, Ford F-150, Lincoln MKZ, and Mercury Mariner, along with many Chevrolet Malibu and Buick Encore platforms. The relay’s 70 amp rating, square connector, and 4-terminal blade design make it a practical replacement when the original relay matches those specifications.

This part cross-references Four Seasons 20756 and FEL-PRO 36146 for the same application. Standard Ignition RY-790 is also referenced by part numbers 1R2099, AR6295, DR1100, F80B14B192AA, R6295, and RAA1757.

What It Helps Fix

• Intermittent relay operation in computer-controlled circuits
• No-start or no-power conditions caused by relay failure
• Electrical accessories that stop responding under load
• Heat-related relay contact wear in the underhood fuse/relay area
• Voltage switching problems in 12-volt systems
