Exterior lighting

I have a head scratcher for all of you.  I just replaced all of the sockets for the turn signals, and tail lights on my 74 Torino.  As I was replacing sockets, I tested each one as I did the install to make sure that they were all working properly.  As i got to the last one, I had my son turn the lights on, and they all came on for about a second or so, and went out, with nothing happening after.  It looked like that there was a 15a fuse that blew for the brake lights, so I replaced it.  Still nothing anywhere.  No turn signals, no brake lights, and no running lights.  I did see on the final socket where I had wired two of the wires backwards, but I corrected that before I replaced the fuse.  Still nothing.  What's truly aggravating is that all of them were working properly until I changed out the final socket.  Then they all went south.  Is there something else that I'm missing?  I've dug through the schematics for the car and haven't found anything that could possibly be causing this.  I could just be blind as a bat too.  That's been known to happen.  Any help trying to trace this down would be tremendously helpful.

Do the hazard flashers work? That's a separate circuit path with a different flasher unit.

Hazards do not work either unfortunately.

I havent had a chance to pull the switch itself and get to the connector properly.  I was able to find the input line and poke a pinhole in it to get a reading on it.  I will pull the connector so i can see what i'm getting on the output side of the switch.

I have more info.  I have power to the turn signal switch as long as I have my meter on the body directly.  If I put it on the ground wire at the switch, nothing, which tells me I have a bad ground somewhere.  The question I have is where exactly is it grounded at?

There are ground wires in the trunk on the harness I think on the rear bulkhead cross piece. At least I think there is.
