I am going to go out on limb and say that you are trying to activate the 12 volt accessory circuit on the 7-way of your 2007 GMC Sierra 1500 and it isn't working so you are looking for a fuse to replace?
Actually what is happening on your truck is that there are a few underhood connections that need to be made in order for this circuit to be completely activated.
For more info on this check out the FAQ article I attached to the right and scroll down to the section titled, "Finalizing Connections for the Brake Controller."
If you do need to find the fuse you will need to check the diagram that is on the lid for the fuse box.
