I think that there are several good kits out there. You will get responses that recommend every one of them. Most if not all, have wire that is marked every 6" to define it's purpose.
Most use GXL, SXL, or TXL crosslinked wire. that is what you want. Stay away from PVC Hook Up wire - the insulation has a lower melting point than the crosslinked wire.
No matter what kit you buy, you still need lots more "stuff". Look at using relays on your headlights, fan, and electric fuel pump. You'll need wire loom to protect the wires. Wire ties, shrink tube, terminals, connectors and a fusible link. Some of these things are included in the kits - some are not.
There is lots of difference in shrink tube. The stuff you buy at the swap meet is single wall 2:1 shrink. The good stuff is double or triple wall with adhesive. when you shrink it an adhesive melts and completely seats the joint. It is available in 3:1 and 4:1 shrink. From the right source it isn't much more expensive than the cheap stuff.
I have had wire loom and wire ties that gave up in a year or less. OEM wire loom seems to last forever. I don't know how to tell the difference, But I don't buy the stuff from HF or the swap meets anymore.
Location: If you're old enough to need reading glasses or bi-focals, mount the fuse panel somewhere that you can see it, not high up under the dash where you have to take the seats out and get a magnifying glass to change a fuse. (See my avatar)
