Reman cluster works on '03 but not my'06

[Autometer]

Sup guys, this is bugging the crap out of me.  Got a rebuilt cluster in my '06 silverado 1500 and only the voltmeter doesnt work.  On the plug, im getting voltage to the orange B11 and pink wire B9.  I've tried the cluster in my neighbors '03 and it works fine.  I reached out to the supplier and they said as long as it worked in the '03, its good.  

 

 

 

I've tried to bench the cluster.  When I probe B11 pin, the voltmeter guage will glitch and move slightly to rest at the 9.  When I probe B9 and B11 simultaneously, it does the same cycle and the batt light comes on.  

 

 

 

That is all it does in the truck.  Running, the batt light goes off and all other guages work as they should and the voltmeter just sits there on 9.  My batt and charging voltages are fine btw.  Since my truck has the variable voltage regulator deal, is there something else that triggers the voltage reading other than the B9 and B11 pins?

 

 

 

The reman cluster has the same part number as mine, so I assume its the right one.  My original cluster, only the speedo and tach work, the reason for a reman.
