Tach for 6.9

I have 1984 F250 6.9 diesel.
It came with no tach (stock)
so Im thinking I want to install an original tach.
Is hard to install? My truck is all apart to restore.
And where can I find one??

Thanks

If the diesel is like the gas vehicles, the truck is wired for the tach. Go to a salvage or find one on e-bay and it will go in in place of your existing instruments.

I believe there's more to it than just that, Gary; I think he'll also need a sending unit and maybe one or two other components, I don't remember for certain (but I've seen it talked about here, searching the archives might give some good info).

My mistake. Guess I'd better stick to something I know about.

I have a spare tach and circuit for the instrument panel. You would still need the tack pickup for the timing cover

A diesel tach also shows a different redline than the gasoline tachs.

I think it would honestly be better to go the aftermarket route. You can get one at almost any autoparts store for around 30 or 40 dollars, and it's an add-on so you can keep the truck "origional" without tearing into the cluster.

Personally, I do too, and wouldn't mind something to fill the extra space on my cluster with.

Also, I think if you've got idiot lights, you need a different printed circuit and gauges to replace the idiot lights, don't you? Chris? Gary?

From what I've read you need to change out the connector as, apparently, the trucks with idiot lights had a different connector for the gauges as did the other trucks. There's a how-to in the stickies here that should help.

The ones at the parts stores are for gas motors, triggered by the coil. Diesel aftermarket tachs are generally driven by the alternator pulses, but is dependent on the alternator rpm matching the crank rpms.
