Dome lights and radio not working

We put on some cab lights on last night on a buddy's 2001 Dodge diesel and now the radio and the dome lights are not working. We couldnt get the lights to work from some reason with the 5 amp fuse, so he decided to try and wire them up to the wiper 25amp fuse. well that was to much power and melted the wire and blew a fuse or to. So I had to rewire everything and it worked with the 5 amp (not sure why it wasnt working in the first place). But now the dome lights and the radio are not working. He said he checked all the fuses this morning and all of them were good. Is there soething we are missing? Are there anymore fuses other than the ones int he door and under the hood? He checked all the clear fuses, but what about the big square metal ones? He just bought this truck and this stuff isnt working and I think it might have to do with when he tried to use that 25 amp fuse.

What are we missing here?

Oh, and me and another guy put the exact same lights on his dodge the exact same way and they work perfectly.
