Are you trying to guess or you really know ? According to the service manual it's pretty straight forward. Ambient temperature gauge is connected directly to the combination meter. The meter itself in diagnostic mode switches on temperature segments. I suspect the only thing you should do after sensor installation is to activate it via Consult III. The main problem is where to get this device from, it's too expensive

im going to venture to say that the gauge cluster(speedometer) is already programmed to accept an ambient sensor. I highly doubt that they would have 2 or 3 different clusters. I think its all the same one - and all you need is the actual module to plug into the wiring harness.
-why would they wire all the cars for them and then install different clusters? save money on clusters, but not wires? doubt it!
my guess is buy an ambient sensor plug it in, and see
what happens. if it doesnt work - then you might require your cluster to be programmed by the dealer via Consult
