Fuse panel

I have lost my diagram for the fuse panel. My back brake lights are not working. I am missing a couple fuses so I can not tell. Can you please tell me which fuse is for the lights. PLEASE help :)
Do you
have the same problem?

I had a stock fusable link burn up on me. It is on the second from left post in my junction block. Does anyone have a diagram for 5.7 junction block. It's is not the ctsy fuse or the alternator. When I replace the fusable link it started and then the next time nothing. Some cargo light and running lights are still working. I am thinking it may be the ignition but would really like to see a diagram or hear from someone before I go about taking it out of the column

The one i'm sending is fo rthe power dist system which could effect starting see if it's getting power and if not see why it is blowing by checking for a draw. It should be the same size as listed otherwise it may be to small also check your ignition switch it could also be just aplain old bad starter.
