how to replace
What is the correct part number of the engine fuse box for a 2004 and how do you replace one?
for relay 43 and 45, does the notch go on the top or on the bottom?

Why are you replacing your fusebox ??…if you want the correct part number I’d stop by your local GM dealership and ask the parts guy…a relay if a 4 blade can go in either direction and work.

The reason for replacing is that the plastic had melted from relay 43 burning up
