After you install a pickup to make the electrical signals for your engine, its a done deal. But, to get any tach you want to work, you'll have to install a hall effect pickup. You can get these thru Dakota Digital, IssoPro, and several others. I always mount my pickup in the bell housing area to pickup the flywheel teeth. But, if you don't want to go thru all that, there's a pickup that mounts to your alternator. You can get it thru Autometer.... However, you can get The 4500 RPM Diesel Tach and the pickup (Sold together as a kit) for a little over $100 from Autometer....
