SW Tach wiring?

[67 GTO]

I've got a Stewart Warner (panel mount) tach. Does it use a sender? If so, can I use the sender from a 2 5/8" tach? Any links to wiring diagrams?

Thanks, Peter

Yes, a panel mount uses the same sender as a pedestal mount... if using it with a standard GM ignition, this would be a 990B monitor box.

This might be a dumb question, but would this (pic attached) box be of any use? http://www.yenko.net/ubbthreads/images/graemlins/dunno.gif Number is 429375...

Depends on which Tach you use....It will not work on a 970 series tach.That one will require the 990 A or B sender....What tach do you have????Looks like a 960 from the rear....If it is a 960, it is a solid state unit that does not require a sending unit....

Tried to learn what I could (before asking), but other than figuring out that it's a panel-mount, and it has the green line... http://www.yenko.net/ubbthreads/images/graemlins/dunno.gif

Tach face pic included now. If it's self contained that'd make life a little easier. http://www.yenko.net/ubbthreads/images/graemlins/burnout.gif

Yep,it's a 960.......Good luck! It might be a little slugish.Most are from what I've found. Solid state is not quite that 40 years later...

Thanks guys! Knowing what model it is made a big difference, I'll test it this weekend.
Ironically, after a quick search (using Google) the info I needed came from none other than 68l30! http://www.yenko.net/ubbthreads/images/graemlins/worship.gif Posted here (http://www.yenko.net/ubbthreads/showflat.php/Cat/0/Number/18602/Main/18552) back in '02...

We have found they are sluggish on the bottom end and go crazy when turning the revs up quickly. In the Yellow beast we run a similar looking tach, but cable drive. Good thing about those, alot cheaper then the ones that require a monitor. In fact, we have two, one a gift from another supercar owner. http://www.yenko.net/ubbthreads/images/graemlins/biggthumpup.gif

I had one 960 rebuilt with today's high tech guts.....Still a little off http://www.yenko.net/ubbthreads/images/graemlins/crazy.gif...Use them for what they are,COOL...
