Does anyone know what the dip switch settings are for automatic and 5-speed cars? My spare 91 164L automatic cluster switches are set at 1-2-7 down and 3-4-5-6-8 up. I read once that a switch is set one way for AT cars and another for 5-speed models for speedometer. Switches are inside cluster at tach side of circuit board. There is one pot inside also on speedo side of board.

There are two external adjustment holes for pots one near tach and one near speedo sides. Blue dot in picture is location of pot adjustment on speedo side.

There is an Alfisti asking as he thinks his speedo is slow in his AT model.
