I had a spare pigtail for my Garmin from a previous dual sport install and soldered the two together. The BMW pigtail does come with barrel crimps and waterproof heat shrink tubing.Hi, i have seen the BMW part in person and have ordered one. Question to you, did you crimp the wires to garmin outlet plugin? or, how did the garmin connect to the other end of the BMW part? loose wires?
