Replaced my turn signal switch now my gas and temp gauge peg!

I took my '74 Duster out last month and on our way home I caught a slight hint of a burning wire when we pulled up to a stop sign. It quickly went away but, I was on edge. We got a couple miles down the road and found that when I turned the wheel almost all the way to the left the horn would honk like I had a short in the steering column.

I ordered the replacement turn signal switch and swapped it out today. I finished everything up and when I turned the key on the gas gauge pegs pegs on "full". (It has about half a tank in it). I shut it off before I damaged the gauge. I pulled it all back apart and didn't see where I pinched any wires. I put it all back together again and this time I fired it up.

With the engine running both the gas gauge and the temp gauge peg like they are shorted. Everything else seems to work fine.

Anyone have any clues what happened? Hopefully the weather will hold out and I can start driving it again!:D
