Requires E38/T43 reprogramming for proper operation. Not compatible with E67 setups!
Add pigtail? Select "Yes" if you're not using a Speartech powertrain harness with the Tap Shift plug built into the harness.
If using this for a Twist Machines Shrifter, you must select "Yes" to "For use with Twist Machines Shrifter" You do not need to select Yes to Add Pigtail!
If you don't have a Speartech harness with the TapShift plug on it, please see
