Tachometer Help

-
There are many ways to mount a tach. I used a bracket that slides under the dash pad and ran the wires thru the vent. Search the forum, there are several threads about this.

Steven190, where did you acquire the slide mount for your tach?
 
Here. There is a member that makes them. I thought it was a female in Florida, but that has been awhile and my memory i getting bad.

Younggun2.0 was going to make one for me, then he was going to sell me the one in his car, then he dropped off of the radar.
 
I’ve seen a few A bodies with the old big hose clamp on the column with the Sun Super tach on the left side of the std. speedo. No one worries about the speedometer below 45 mph or so.
 
Sun Super Tach in my '69 cuda which is almost as old as the car

In my humble opinion, again depending what you're using the tach for, it should be mounted so that your eyes are not distracted from the road/track ahead and that you're not hunting for the tach. Obviously the shift light lends itself to this fact because no matter where the tach is mounted you're going to see the light come on which indicates your shift point.
 
I'd like to out a tach in my '67 Barracuda where the factory vacuum guage is. Has anyone doe that? I see that Classic industries has one but wondered what it takes to do it.

Pull the inst panel is the only hard part. How to is in factory service manuals. The vacuum performance gauge has only a vacuum hose attached. Take it out of the firewall, plug that port in the intake. You'll need a different grommet in the hole for the tachs signal wire, or thread the wire though a length of the rubber vacuum hose in that grommet. This wire goes to the coil. The tach needs a switched 12 volt source also. The factory added another fuse in the fuse box for the tach but you could simply tap the switched 12 volt wire that feeds the BRAKE warning lamp. Add a inline fuse hidden behind the column door/filler. Write tach on it with a sharpie. I dont know about aftermarket tachs but the OEM tach had two contact studs. They were not marked which is which. The shorter one is signal. The longer one is the switched 12 volt.
While you're swapping the vacuum gauge for a tach,,, notice that 2 of the 4 illumination bulbs are on either side of this center pod. The vacuum gauge aint much. Light can pass right through it. The tach is solid and probably raw dull gray metal ( if like OEM ). In my opinion, the factory should have painted the tach housing white just like the plastic blank/filler for this pod is white.
