The same size fuses as in our 3rd gen fuse boxes. I need a big fuse for my amp and the wiring kit I bought uses this type of fuse. If I don't find the right rating I will need to change over to different style of fuse.

Thanks

 

I don't think you got the right wiring kit for your amp then. If you need 40-60 amp fuses, a proper wiring kit should have come with a Buss (the big ol' cylinder thing) or Maxi (look like a Mini, but big) fuse holder. I hope your main power wire is 2 gauge or better for that kind of power...
