I had the opportunity The last couple of days to make a little progress. I got the crank reluctor mounted and I think I've got the "0" position figured out.

Here's some pics of the reluctor and crank position sensor.
As soon as I can get the engine back in the Jeep I'll start running wires.

I'm going to be using the cam sensor from a 2004 4.0L engine. It's a drop in part and gives a 1x signal.

I fired it up today. It sounds really good. It started pretty easy once I got every thing hooked up.
It's idling at about 1100 RPM but I expected it to be a little off from all the different sensors I'm using. I'm guessing at the RPM, I haven't hooked up the tach yet.
I have to run the OBD2 port wires so I can read the DTCs to see how it likes running on 4 coils and 4 injectors. And I've still got to hook up the exhaust, so it's loud. LOL

It went from this.

I'm hooking my fan up and I'm wondering, are the fan wires from the PCM + or do they ground the relay to turn the fan on?

I given up on using the Jeep throttle body. I just can't get the IAC to work with the GM computer.
The lowest I can get it to idle is @1100 and it's always changing 100 -200 RPM.
I made an adaptor for the throttle body I have from a 2004 4.3L V6 and it works good so far.
It's idling at 650 -700 RPM just like it should be. I'll be installing my wide band and gauge tomorrow so I can start tuning it.
I've turned the MAF off for the moment. I've never done that before and just wanted to see how much it affects it.

After putting the GM throttle body on this engine and how it responded, I think I need to get another one for my 4.0L in my truck, that I'm running on a P59.

Thorwon, what changes did you make in the bin to run on 4 coils?
