Keep critical circuits switching cleanly with the Standard Ignition Relay RY-193, an electromechanical relay cataloged for A/C compressor control, fuel injection, and fuel pump duty. It installs as a direct-fit replacement across a wide range of late-1980s to mid-1990s Chrysler, Dodge, and Plymouth cars, vans, and trucks — including the 1989-1993 Dodge Dakota, 1994-1995 Dodge Ram 1500/2500/3500, and the 1989-1991 Dodge and Plymouth minivans.
A relay uses a low-current control signal to open or close a separate higher-current circuit, so the controlled load doesn't have to run through the switch or module that commands it.
- Triple-role design: listed as an A/C Compressor Control Relay, Fuel Injection Relay, and Fuel Pump Relay for the applications below.
- Switching function: makes and breaks the controlled circuit on command from the vehicle's control signal.
- Direct-fit replacement: for the listed applications.
If a failed relay is the cause of a dead fuel pump, a no-start, an A/C compressor that won't engage, or intermittent electrical operation, this replaces it. Because these symptoms can have other causes, diagnose the circuit before replacing.

Frequently Asked Questions
What does the RY-193 relay do?
It is an electromechanical relay that uses a low-current control signal to open or close a separate higher-current circuit, so the load doesn't run through the commanding switch or module.
What circuits is this relay cataloged for?
It is listed as an A/C Compressor Control Relay, Fuel Injection Relay, and Fuel Pump Relay for the applications shown in the "Vehicles it fits" section.
Will it fit my vehicle?
It is a direct-fit replacement for the listed applications, including the 1989-1993 Dodge Dakota, 1994-1995 Dodge Ram 1500/2500/3500, and 1989-1991 Dodge and Plymouth minivans. Check the "Vehicles it fits" section.
Could a bad relay cause a no-start or dead fuel pump?
If a failed relay is the cause, replacing it can restore the circuit. Because a no-start, dead pump, or non-engaging A/C can have other causes, diagnose the circuit before replacing.
What is the manufacturer part number?
The manufacturer part number is RY-193 from Standard Ignition.
