Wires, wires, wires - get yer wires:
http://woogeroo.home.mindspring.com/autolinks/wiring.html I'm going to add that EZ wire one also... cool.
It's a Snap Wire and Cable <- they have a really small fuse block with wires for less than $200 - I think, last I checked. I do not know anything else about them.
also several of the vendors sell the repro kits - basically the same kit at different prices.
