you are correct.canuckrider said:I have an '04 and have the Baron's tach as well. I did not need any adapter. I beleive that it is the '05 and newer C50's that need the adapter because they are a different ignition system. If you don't have the adapter on the newer ones, your RPM will only read at 1/2 of actual.
You should be good to go, as far as I know.
