Hi Dave, I did not need a tach adaptor (installed it and didn't help) using a 6AL and VDO Vision series tach. I called my VDO distributor and his answer was to flip dip switches (not energized) until I got the right combination (the instructions were worthless). I did just that and it worked! I did not record the settings but could remove my tach to retrieve for you if necessary.
