You don't have one, unless it was added by someone. It would be left side of the battery little black round thing plugged into the 3-wire triangular connector and a short ground wire.

IMO, it would be BETTER to remove the FI and put on a carburetor than removing CL from any ECM. At least the carb will self-adjust for some atmospheric conditions where the now-hobbled ECM will not. There is NO REASON to run anything other than stoic targets in CL*
