I am going to upgrade my Boxster S 2002 ROW with CC stalk, reading sevral treads I found two verison for wiring refere to model yeare 2001-2002.
On the majority there indication to link a wirw from the cluster to DME on soem other is wrote this not necessary doe the fact that after 2001 new instrument cluster does not require this conenction.
Someone as more details?
Or at least on USA cars, I have manufactured many harness to retrofit a 4 stalk. You need a common or ground and the wires that go to the instrument cluster....no need to run any more wires.
