I didn’t document my OEM to standalone conversion in detail as this has been covered numerous times on the www. I do have a few photos with some explanation you will find.
As for the electrical wiring harness and modifications to it to create a “standalone” harness, the best reference you will find is found at lt1swap.com. Brendan has compiled the most comprehensive and accurate collection of information found in any one place.
Another resource that I found invaluable was the Youtube channel of UCanDoIt2. He takes the info found at lt1swap.com and simplifies it in his documentation videos of his “Project Rowdy – Jeep Restoration” project. He also supplies some wiring diagrams that are easy to understand. These diagrams are what inspired my diagrams I have posted here.
Brendan has posted his lt1swap.com videos on Youtube also and they are quite good and helpful.
I encourage you to read through the info at lt1swap.com several times. Take notes if that helps you.
This is my standalone fuse/relay block diagram as I currently have:
This is the diagram for the connector from wiring harness to dash/gauge cluster. For this I used a good quality Ebay special 12-pin waterproof connector:
