Hey guys I am having troubles with getting my tach to work. I hooked everything up correctly but when I turn my car on it just sits at 7000 rpm. no movement at all. any ideas for me? the directions they sent aren't really helpful. I have the model with only the sift light adjuster **** & light, nothing else. Thanks in advanced, just kind of frustrated at this point.

 

its a sign that you should not use such a big obnoxious tach. get an oem gauge cluster that comes with one and ditch the monster tach.

 

You never know, he might have a track car and needs a shiftlight and precise tach. Not everyone buys them for no reason.
Anyway, check the (Green I think?) wire from the tach and make sure it goes to the negative wire off the distributor. Which is the black wire off the coil I believe.

 

its the blue wire.

you can get a shift light seperate from a big *** tach if thats what you need. even if the factory tach is not perfectly accurate i'd much rather look at it over some ginormous tach that sticks out like a sore thumb. whatever floats your boat i guess.

 

If you have a monster tach, your sh*t better be fast!
