I would like to add a small tach to my 93 7.3 idi.Has anybody done this with aftermarket tach? TIA Don

 

I have this one. easy to install. But you need to borrow a timing gun to sync up your RPM's


Auto Meter 2888 Performance Tachometer

 

If you want to use a factory sender, Dakota Digital sells an adapter. The factory sender sends out 53 pulses per rev, which is why a 'normal' tach won't work.

 

Thanks for the help,i will look into those options Don

 

I have a tach gauge in my cluster, and i've tried new pickups but couldn't get it working. I havent had the patience for testing the wiring... The tach will sometimes come to life driving around, without a pickup installed

 

Any electric interference will cause it to jump or misread. Leaky alternator gave me an issue once. It was leaking ac current from the rectifier.

 

Is this a truck or van?

A 1993 van would have an E4OD then, right? So it should already have the tach sensor. Technically, on a van, it would be considered an "RPM sensor", since it's only for the tranny controller. Most likely no wiring for it going into the passenger compartment, since the vans didn't get tachs. So you'll have to tap into the wiring where it runs under the hood. Then it's just a matter of calibration (see thread linked above), and of course, where to mount it.
