I can't explain what is happening. So I just made a video to show you. I'm thinking about taking the dash off. I don't know where to start. I put them led bulbs in and as soon as I turned the ignition I seen smoke come from the cluster.

I am far from an expert but I believe the clusters are somewhat year specific, I know that a 87-88 cluster is not the same as a 93, someone will chime in to confirm, if I'm wrong they will chime in when they get done laughing at me.
You may be able to replace the printed circuit on your original

The cluster wiring changed in 1990.
87-89 and 90-93 are the two different model clusters and aren't interchangeable without resplicing the wiring.
Cluster you show in the dash is an 87/89 unit.
I must admit i watched video with sound off so may have missed something

A friend of mine gave the cluster to me and said try it it might work. It didn't. It's on eBay now for $75 dollars. The only thing that works on the original cluster is the oil pressure and the speedometer.

Take the cluster out and look for traces of bunt stuff. The most likely culprit is that one of the LEDs bulbs shorted or is installed incorrectly.
See http://www.stangnet.com/tech/cluster87-93.pdf for information on the cluster connections and wiring differences between model years. The clusters are interchangeable, but you have to do some trimming & move some wires.

I'm just gonna buy a new 90-93 gt 140 cluster and hopefully that fixes my problem. I don't know if it will or not because when I roll the windows up and down. The RPM gauge and the temp gauge moves a little bit. So you think a new cluster would fix it ? Or do you think something else behind the dash got messed up?

The secondary power ground is between the back of the intake manifold and the driver's side firewall. It is often missing or loose. It supplies ground for the alternator, A/C compressor clutch and other electrical accessories such as the gauges. The clue to a bad ground here is that the temp gauge goes up as you add electrical load such as heater, lights and A/C.
