New cluster did not fix the dead Gauge issues HELP

Uuggg. So replaced the temp sensor today, cleaned the connector female piece (attached to the sending wire), started her up, and nothing. No movement whatsoever on the temp gauge. Now I am at a loss.
Keep in mind this is what I have:
New IVR
New Cluster PCB
New Temp sensor

Gauge works when I ground it out, so we know power is getting from cluster to engine temp sensor. If I use Multimeter and check voltage at engine sending wire, I am getting fluctuating voltage.

What can I try next?
