Where is a good place to put one that does the least modifications to the dash and looks built-in?

 

Try the pivot brand it's small and you can put it anywhere.

Thanks! I should have been more specific, I just need to place a light, don't need the tach sensor, alread have a buzzer and sensor. So I just wanna add a light behind the dash if possible??

 

you could do something like this maby

I'd personally go with an Autometer shift light, and RPM "pills" that they offer in 5k-9k range depending on preference and redline.

 

like i posted, check out that link you could easialy wire that up and make it work.....

 

How about the autometer shift light mounted right behind your steering wheel on the gap between that and your gauge cluster/bezel, dunno how to describe it any better but its where im gonna put mine. itll be centered behind your steering wheel and will be very visible.

 

Excellent link, gets me started on how to insert my High intensity LED.

Thanks!
