2005 wakesetter gauge cluster

[redrooster]

Hello all 

I recently sent off my digital gauge to gauge savers for repair.  The perfect pass gauge was connected only with a Grey wire.  Seen in first Pic.  

In second picture there is an extra connector and blue wire that are not hooked up to anything.  What the heck!!!

The grey wire is perfect pass specific and not through the medallion system. Completely normal if running 6.5+ng (post 2006)

So then what is the other white connecter for?  And the blue wire??

The blue wire is extra on mine too.

The extra plug did likely go to the factory 2 line perfect pass integrated into a factory gauge (I forget tach or speed)

Blue wire will be a gauge backlighting supply. When you turn on nav or interior lighting it'll go live (12V +ve).

The Medallion harness usually includes several spare plugs to run additional gauges.  It is a digital bus, so all of the plugs have the same data on them.  It doesn't matter which gauge gets which plug.
