Default Electrical questions/problems...

...ok, while trying to fix my fogs, something happens (even with my battery disconnected), and several things stopped working. All fuses check out ok, replaced them just in case. I checked the dome fuse several times, ran a meter to it and current is flowing.

Trunk popper, Keyless Entry, Steering Wheel, Door Locks, Memory (for radio), Interior Illumination all gone.

The headlights were working, then stopped, checked the fuses and there is no more power going to them either.

I think the headlight and other problems are on separate circuits, and I read on here that it might be the integration relay. Just wanted to see if anyone had any input or diagrams to share. Sorry if I didn't find it on the SEARCH.

Thanks in advance.

Ok, figured it out. It was a loose relay set, and the cables were not making a good ground from the chassis.

Still have no power going to the foglights. The mission continues.
