Wiring in the new tach cluster and 4x4 indicator

[6 Nebraska IDIs]

Okay guys, I want to get started on doing something with this truck, and I guess I can wire in the tach and 4x4 indicator from my new gauge cluster.
I got the new cluster plug on a pig tail of wires that came with the new cluster.
I do not have any wiring diagrams so could someone explain which pins in that plug are for the tach, and which ones are which if there are + and - wires.

Also, I am doing a 4x4 conversion to this truck, and I'd like the 4x4 indicator to work in the cluster. Which pins in the plug are used for this, and where do I wire them to on the truck? I am swapping in a ZF5 and 1356 transfer case, if that makes a difference.

An old member at TDS by the name of Bill Miller (dreamachinef250) wired up a tach into his truck and he has several good photos covering what he has done. I hadn't heard or seen of Bill in a while....I hope he's OK.

I don't know if those are anything you can use or not.
