BMW SMG to Manual Swap (Fix Cruise Control)

Updated: Jan 9

To properly enable cruise control, the SMG to manual gearbox conversion on a BMW requires a few more steps.

I will walk you through the steps necessary to reactivate your cruise control. The procedures are simple, requiring only a few electrical connections and reprogramming.

  • Make a closed circuit and remove the temperature sensor

  • Identifying connections and wiring

  • Connect the oil temperature sensor to the gear selection switch and test it

  • Check that pin 2 is receiving ground

  • Programming in the manual mode

  • Program the DME

This article will discuss converting from SMG to manual swap and having problems with the cruise control. It's a basic wiring schematic that I'll show you.
