Please HELP 2000 Wrangler

I just bought a used 2000 wrangler sahara 4.0 automatic with 56,000 miles. Just recently When I start it up the airbag light stays on and then when I start to drive (on and OFF) The check engine light comes on. And then all the gauges ( Speedometer, Tach, Battery, Oil ect shuts off and then returns after a few seconds or so back and forth. This has only happened a few times on and off for about two weeks, ANY HELP PLEASE Thank you!!!!

The connector between the dash and instrement cluster is not contacting well. If you take apart the dash (not hard to do) you can bend up (or down) the connector mouted to the dash so it contacts the cluster better.
