I've got that module in my MK3.1. To activate turn signals, I have a pair of electric window momentary switches, one on either side of the steering wheel mounted in the dash located right at the diameter of the wheel. Only the outer portion of the switch on each side are wired such that I activate the signal by pushing the outside of the switch on each side. They are positioned so that I just extend my finger with hands on the wheel. Works very well.
