Hi All, Redoing my 67 dash and making an upgrade to speed warning speedo. The shop book shows very little on this, and I need help !!! Where does the wire go to power this? The shop book show a stud of some sort on the top side of the housing
?? The wire dia. shows this going to the lighter
? Any help would be welcome. Also looking for a sorce for the buzzer and bracket. Thanks, Bruce
