How much is needed?
 

I'm building a VFR 9A. One radio, landing lights, and basically the required six pack of instruments and mostly Vans engine instruments. While I know there are many variables, I need a W.A.G. as to how much wiring and in what gauges I should initially buy. BTW I will be using fuses as opposed to CB's if that makes a difference.

P.S. I wish my wings and fuse would show up already, the suspense is killing me!!!

None. ;) Wait until you have the Fuselage rolled over, decide on exactly what you want to install (electrically) then make your decisions. Lots of help at AeroElectricConnection. Fuses vs CB's no difference.

Jorge,
Come up and see me. I've got loads of extra Tefzel wire in gauges from 24 to 2. I even have a good selection of various colors. I'm in this process now, so stop by my shop and check out my 8A.
