Not much to be said here as I only slightly modified the factory body wiring. I made some wiring changes and tapped into factory wiring for gauges and remote starter. I removed a few wires that were not needed for under the hood in my conversion.
A very important resource for factory A and G body wiring is at Maliburacing.com
Note:
In GMs, all Pink wires are ignition hot. Orange wires are battery-fused. Red wires are battery-no fuse (or maybe a fusible link, depends upon location and service).
Instrument panel connection C183 is the connector that attaches to the printed circuit on the back of gauge panel.
The connection at firewall is the C100 connector.

About to wrap up the stand-alone harness. Literally. Used cloth loom tape to wrap most of harness to keep it neat for looming.
This is the layout I went with. Decided later that I will use a different fuse/relay block next time. This will be under hood so I will have to protect it from water.
Wired, carefully double and triple checked, tested. ready to wrap and loom.
just a couple main battery power wires to add.
