I have one on my 06, I presume its the same for 08. If you have two "free" connections on your CDI, they may be for the map switch. If I remember correctly, there is one male and one female bullet connector on very short leads coming from the CDI. When they are connected together, one map is used, when they are disconnected,, the other map is used.
If you need further explanation, I can try to look at my 06 later today or during the weekend.
