Help Identifying Underdash Connectors

[67TXStang]

I've removed the entire underdash harness from my Mustang. I could use some help identifying a few plugs which were not connected to anything. I'm not sure what they are for and would like to know since I'm going through the entire harness.

If it helps, it is a non-A/C 289 without tachometer.

1. dash cluster for clock and left turn signal
2. radio connector (power and lamps)
3. dash lamp connector for accessories
4. cigarette lighter connector

Thanks Midlife. I knew you would know these connectors.
