Does anyone know what these three fuses are used for on a 2000 Silverado. I found a diagram but it really doesn’t match. This is the fuse box to the left of steering column on floor. Reason I ask is because my new clutch pedal is hitting the fuses slightly. The picture below is an example of what I have.

 

If you mean the Relays. Center is Parking lamp relay. The top right is INADV PWR Relay, below that is CTSY Lamp Relay.

That electrical center is called the Mid Bussed Electrical Center (MBEC)

 

Thank you sir, it was little hard to match for match the diagram and physical layout of the box
