6.2 Diesel tachometer wiring diagram

I am trying to find a diagram showing how the early diesel engines hooked up for a factory 4k tachometer. I tried mister Google and got nowhere. Anyone have a schematic on this?

Didn't they get their signal off of the alternator?

Then there is this from a while ago

Correct, have to have an alternator with R terminal and then the voltage converter. Dakota digital makes an aftermarket converter. I used it on my 78 diesel for years.
