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.

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.

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.
