To identify the model of the oil pump relay, you can do the following steps:

Locate the oil pump relay: It is usually located in the engine compartment or under the vehicle. If you cannot determine the specific location, you can check the vehicle's service manual or consult a professional technician.

Observe the logo on the oil pump relay housing: there is usually information such as model number, manufacturer name, production date, etc. The model number may appear as a combination of letters and numbers, such as "RY-01", "4RD-008-567-01", etc.

If you cannot find the model number on the casing, you can try to disassemble the relay and see if there is a model mark on the internal components or circuit board.
