Fumblin,
there is very interesting reading and exciting too! We are all looking forward to that first roar of life!
The way the truck should be wired is:
A short braided strap between the starter frame bolt and the truck frame, a heavy braid between the battery negative and the frame, and a battery cable between the battery positive and the starter.
You should charge up the battery to full. Most places that sell to areas with farms will carry a 6V charger. Also, you will not get good current flow without solid bolted connections. If you want to see how fast it will turn over, take the plugs out and give that a go.
