Car wont crank after dashboad removal

What is your question?

I was going to replace my dash board off with the old and and in with the new. I only connected the speedometer and the switch to turn the headlights on. The car turned on everything was normal. The next day I changed my mind and put the old dashboard back in. After completion the car won't start. The Gauges turn on but shuts off when trying to start. I can hear the relays clicking on the passage floor board fuse box. My battery is draining quicker than normal at this state. I changed all the relays and fuses at all 3 different fuse box locations I have 2 batteries fully charged the voltage read 12v.

What makes this problem better or worse?

Nothing
