Hood cable ground issue

[waynelash]

I was finishing my oil change today and I noticed getting in that it said my hood was open which I thought was odd because I closed it. Opening the hood I found the ground strap was ripped off from the connection on the firewall to the hood, now my turn signals don't work, fog lights, high beams and even my dome light switch. Is this also a ground for some pieces of the interior? My cluster and radio works fine just doesn't shut off when the truck is off.
