2002 SD under hood fuse location?

[Hercules-550]

I lost all functions for trailer lights. I tested my plugs and got nothing. I was told there is a distribution box with fuses and relays under the hood. I can not find it. Does anyone know where this is? Pic of location would be great. I am lost and need to use my trailer tomorrow for work. Thanks for the help.
I checked the fuses the book listed and they are all good.

No (stock) fuses under the hood in an 02, 2 relays I know of, besides GPR/AIH, both in the black box in the 2nd pic IIRC. There is a fusible link on the fender as well, but that wouldn't cause your issues.
