How do you know which fuse is which?!, Resetting your Air/Fuel Mixture Ratio Options

[welc]

Hello!

I want to reset my Air/Fuel Mixture Ratio, as in the how-to-do article, but don't know which fuse is which;


"If you've noticed lately your car has been running awkward or idling at very low rpms or even idling roughly, then your ECU needs to be reset. It is also a good idea to reset your ECU if you've added any performance mods like headers, intake, exhaust; doing this will let you take full advantage of your mods and reset your Air/Fuel mixture ratio so that you can get more horsepower and better gas mileage.

Here's how to reset your ECU. First, start your car and let it warm up. When it's reached it normal operating temperature, turn the car off. Then, pop the hood and remove the Relay Fuses box cover and remove the following fuses: The Hazard fuse, the EFI fuse, and the ECU fuse. Take them out and leave them sit out for 1 minute. Then when the minute is up, put the fuses back in and start up your car. At this time the ECU is being reset so you can take advantage of your mods and get better gas mileage. When you start it up, let it run for exactly 10 minutes, then turn your car off. then start it again and you wil notice your car idle better and from that point on you will now have better gas mileage and your mods will be put to use"


So to my question: How do you know which fuse that is the The Hazard fuse, the EFI fuse, and the ECU fuse?
Don't have any manual so can't look there.
