More info
I have used this thread quite a bit for ideas on my build. Some of the trials and failures have centered around where to route and mount wiring, ECU, battery posts, etc. These things are hard to see in pics and difficult to describe in the threads. Where are you guys putting your ECU? Where did you mount the fuse and relay box(es)?
On the inner passenger fender I added remote battery posts b/c it's a PITA to charge the car, especially if the battery dies with the electric locks. My relay box for the fuel pump and fans was also on the passenger fender but now I want to move it as the A/C lines will make them impossible to get to easily. I have another fuse box on the drivers wheel well. The ECU is on the firewall beside the brake booster. How about the hydraulic clutch master cylinder? Brake booster upgrades? Remote injector coils? There is limited room in the engine bay and sharing these things should help future swaps more functional after assembled and maybe look less "thrown together".

My motor is a GM Crate LS376. A lot of the engine and accessory mounting is from suppliers that don't exist anymore but at the time there was a thriving aftermarket.
As to your question, my 69 is non-AC and there was a lot of room behind the passenger dash pad, so that is where I put everything. I cut the starter battery lead short, brought it to a post through the firewall and then jumpered it to a post back out through the firewall to the starter. That gave me +12 supply voltage inside which I supplied to another fuse box for all the stuff that got added.
This picture is from early on when I was figuring out what went where. I have since put proper connectors on everything and tucked it away under the pad.
Here's an early picture of the battery cable through the firewall.

Thanks for resurrecting this thread. When I built my car seems like there were a lot of LS conversions. Very few went carbureted which is what I did. Not sure I would make the same decision again. There was however a useful forum on carb'd LS motors at the time which I used a lot.
