my car has dummy lights no clock, and the 3 gauge cluster on the center console as well, I picked up an OEM tach a while back and am wondering what all I need to to do replace the dummy lights for the tach?
Just call me Merlin.I am in the same boat, and I'm here to tell you that you're better off sending your 'dummy light' cluster to Bob at Rocketman's Classic Mustang Innovations (http://www.rccinnovations.com/index.php?show=menu-mustang-all) He'll convert your dummy lights to a damn-near perfect replica of a factory tach.
Basically, you'll need a whole new dashboard wiring harness from a factory tach-equipped car, because the factory tach cluster won't plug-in to your non-factory-tach harness (I already tried). I've heard it can be done, but it will take some crazy wiring wizardry to make it work.
Hope this helps.
Hey Merlin,got any idea's to share?I have mechanical engine gauges in the center,same dummy light cluster,I have a tach cluster,any way to put that tach in with the standard style speedo panel & make the tach work with the brake light? :-/Just call me Merlin.I am in the same boat, and I'm here to tell you that you're better off sending your 'dummy light' cluster to Bob at Rocketman's Classic Mustang Innovations (http://www.rccinnovations.com/index.php?show=menu-mustang-all) He'll convert your dummy lights to a damn-near perfect replica of a factory tach.

Nope. The tach circuit board is a replacement for the one on the back of the tach cluster itself (which I'm guessing you already have). The plug itself is the problem - they are different on the different clusters (which means, non-tach cluster only plugs into non-tach wiring harness... and vice versa). At the very least, you'll need to obtain a plug from a tach-equipped car, and figure out how to wire it in to the non-tach wiring harness. THAT'S the hard part I'm talking about.Wiring is no problem for me, and I already have a factory tach. I see that cjponyparts sells a tach circuit board for the car, is it as easy as swapping that for the dummy light board?
I see, if there's a wiring diagram somewhere that says what wires do what I'm all over it! I have some other electrical issues under the dash to chase as well, so maybe if its too bad I might consider swapping the entire under dash harness all together, or build a new one at the leastNope.

Hopefully, "Merlin" will have some advice for you. rofl
