Engine Coolant Gauge Illumination

[delhusband]

HI,

Yesterday I removed and replaced the instrument cluster, disconnecting and reconnecting all 3 plugs.  
Tonight I've noticed that illumination is out for the Engine Coolant temperature gauge.  I've got a circuit diagram for the combination meter, which only shows one bulb for illumination, so don't understand why the Engine Coolant section isn't illuminating, what am I missing?

Sorry, found it.  Can see now there's bulbs per section, missed that yesterday. Case closed
