No Electricity On Crank Up After Removing Cluster!

Ford unfortunately ties the charging system into the cluster. There are several wires going to your alternator. The one that controls the alternator runs through the charge fail light on the instrument cluster. If that circuit is compromised, then the alternator will not operate. This design terrorized me after I installed my last engine. It took me forever to figure out that my alternator was not working because the printed circuit on the instrument cluster had burnt out. Pull the instrument cluster back out and ensure that connection is working properly. I have a pushrod SN which has a slightly different instrument cluster, so I can't give you specifics on it. It will have a connection that goes through both the light and a resistor. Check the continuity of that circuit and ensure the connects to the harness are clean.
