Labuan is an independent state; a federal territory.
It was a part of Sabah until the late 80s, if I remember correctly.
Which should mean that SL/SL####A plates are pre-80s. 
L was the first batch of the new generation of Labuan plates after gaining federal territory status.
After L1~L9999, there was LA, LB, and currently, LC. 

the old plate of sabah was EJA under the rulling of British.

DU 2 - Honda Accord

After L1~L9999, there was LA, LB, and currently, LC.

eh, I thought Labuan one started with L (single alphabet) ?

There are SL and SL#A series also.
