Im a 20 y/o dude from Germany who has owned an MB3 as my first car for about a year now, and am now looking to maybe improve it a little bit, because I have taken quite a liking to it, and this forum seems like just the place.
Yes, I used it just a few days ago, it worked like a charm, and what worked for me was briding the two pins as shown in the picture in the guide, and then turning on the igniotion afterwards. That made it start blinking.
