Wiring advice

[65k10]

Howdy. I'm at the wiring stage of my build. Got a Ron Francis kit and was looking for a little advice on where to run the wires. Such as, running them across the firewall vs inside the dash, low on the inner fenders or up high, or just copy where the factory wires ran. Figured I'd seek out the suggestions of folks who've already been down that road. Pictures always helpful.

Thanks.
