OK so I'm back working on the '50 and I'm ready to rewire the truck. Some background on this 4-year project:

This is my first restoration and quite a learning experience. Truck has been taken down to the frame. I’ve done everything myself except engine short block, head upgrade and body work. I did weld in panels but left the balance of the work to a pro. Upgraded the torque tube rear end with a Patrick’s kit and installed disc brakes on the front. The engine is a 235 out of a ’55 Bel Air. The truck was painted while disassembled and is been reassembled and is 90% complete. I'm ready to do the electrical. I've purchased a new wiring harness from Kwik Wire. I'm converting to 12 volts and purchased a voltage reducer for the fuel gauge, changed the heater motor to 12 volt, have a DA plug for the alternator, a 12-volt coil and 12-volt light bulbs all around. The alternator is in place and I’ve actually test run the engine prior to reassembly of the body. All external lighting is in place.

I’ve installed the fuse block to the inside of the firewall and have the basic wire batches run to their respective areas. The inside is completely gutted so I have full access to the interior. The dilemma is that I sat down and after looking thru the Kwik Wire instruction book realize that I’m completely lost. My knowledge of electrical is extremely limited and the manual was Greek to me. My question is should I call on a professional or is there a good web site that can take this down to the most basic of tasks? I’ve searched this site and several others and it appears that the assumption is most of us have some basic knowledge in electrical. I want to add that I do not have the old harness (it got pitched in the trash during a move). So I have little frame of reference.
Thanks for your input.

It never costs more to ask and it never costs more to think big.
