Designed to switch circuits such as the horn and A/C compressor clutch on command, the Standard Ignition Relay RY-862 is a direct-fit replacement for the listed applications. It fits many vehicles, among them the 2007-2021 Chevrolet Silverado 1500, 1999-2008 Ford F-150 and 2007-2021 GMC Sierra 1500.
A relay is an electrically operated switch. A low-current control signal energizes its coil, which closes contacts that carry the higher current a circuit needs. Depending on the vehicle, Standard Ignition catalogs the RY-862 in several roles:
- A/C clutch relay: switches power to the A/C compressor clutch.
- Accessory power relay: switches power to accessory circuits.
- Horn relay: switches power to the horn.
- Temperature control relay: switches power within the temperature control circuit.
Signs a relay may need replacing include a horn, A/C clutch or accessory circuit that does not operate, works only intermittently, or will not switch off. These symptoms can also come from a blown fuse, a wiring fault or a failed switch, so diagnose the circuit first. If the relay is the cause, the RY-862 replaces it.
The listed applications use one relay. See the "Vehicles it fits" section for the full list of vehicles.
Frequently Asked Questions
Is the Standard Ignition RY-862 a 1999-2008 Ford F-150 relay?
Yes. The RY-862 is listed for the 1999-2008 Ford F-150 and many other vehicles. Check the "Vehicles it fits" section for your exact year and model.
Does the RY-862 fit the 2007-2021 Chevrolet Silverado 1500 and 2007-2021 GMC Sierra 1500?
It is listed for the 2007-2021 Chevrolet Silverado 1500 and the 2007-2021 GMC Sierra 1500. The "Vehicles it fits" section shows the full application list.
Which circuits is the RY-862 used for?
Depending on the vehicle, Standard Ignition catalogs it as an A/C clutch relay, an accessory power relay, a horn relay or a temperature control relay.
What does a relay do?
A relay is an electrically operated switch. A small control current energizes its coil, which closes contacts that carry the higher current a circuit such as the horn or A/C clutch needs.
What are signs a relay may need replacing?
Signs include a horn, A/C clutch or accessory circuit that does not work, works intermittently or will not switch off. A fuse, wiring or switch fault can cause these too, so diagnose the circuit first.
