Speedometer dead after a heater core change.
 

I have a 2002 XLT 3L. My heater core had a leak, but in the process of replacing it I must have broken something with the speedometer. The cooling system works fine now, with no leaks, and all the other gauges, radio, etc that I had to unplug to get to the core work fine.

The only problem is the speedometer doesn't work at all, and the airbag warning light blinks. I was very careful and thought I had reconnected everything, but I must have missed something. What does the speedometer connector look like? I've removed the instrument cluster and am looking around in there and can't seem to find anything that is loose and unconnected.

Thank you to anyone with info
