If you had a speedometer with a tachometer and you replaced it with a speedometer without a tachometer will it work?
it sure would work.. behind the dashboard are plugs for each
function. one for tachometer, one for speedometer, fuel, water
temp. ect.. if your new dash doesn't have a tachometer it will not
interfere with the speedomet aspect of it. but you will not have a
tach obviously. that sucks kid
