Adding Fog Lights - Wiring Question

I am adding some fog lights to my truck, I need to know if it is advisable and safe to attach the positive to the post on the underhood fuse box – it is under a clipon plastic cover. That is only easily accessible + post I can find. BTW it is on a 6.8 Superduty.

On mine I just attached it to the positive terminal directly on the battery with an inline fuse.

It has a inline fuse and all, I wanted to know if it being attached there could effect the PCM or other electronics. There is not anyplace to attach it on the factory battery terminal either - this would have been my first choice.

if its just a truck, then I would crimp on a large loop terminal and put it on the battery post and put another nut on it to hold it.

I would not mess with the fuse box go to the battery direct and put the fuse close to the battery. You can just ground it to the frame.

You mean a loop large enough to fit onto the battery post and not mess with the factory battery cables?

Use a ring teminal large enough to go over the bolt on the battery terminal (5/16" hole?). Either remove the existing nut to add the ring terminal, or if there is enough exposed threads on the bolt, slip the ring terminal over the bolt, and add another nut to hold it.
