Cool. You should really like having all new wiring. At least you will AFTER the work is done!
One thing to make sure of though, if you haven't been told ad-nauseum already, is to add grounding straps to the dash.
They're funky enough when they're bare, but with all the new powder coating on there, you will have to be sure to make your own grounding scheme. Whether it's just an extra screw with a spot ground clean of coating, or welding a stud to it and making sure that the coater does not coat over it, having a good ground between the dash and the rest of the body will make your life much easier.
The dash, instrument cluster, windshield frame and radiator core support are all common areas of failed connection to the ground system. Rust, dirt, separation anxiety and just plain old age wreak havoc on metal connections.
Have fun.
