Electrical nightmare--HELP!!!!!

[Kantosensei]

This is nothing short of an electrical nightmare. I just replaced the under dash wiring harness with a used one purchased from a board member. It installed perfectly. The problem is the old one that I removed was spliced, diced, chopped and probably a whole lot of other related words. The major splices were to the wires going to the ignition switch, which included a splice from the back of the fuse box into the one of the white and red wires. After all was said and done, I tested the lights, heater, radio etc.. Everything worked fine. I went to start the truck and nothing. I have triple checked all connections. Under the hood is another nightmare. To the right of the speedometer cable is four wires, red, blue, brown/white stripe, and black. These four are just chopped off and taped up. Coming off of the bulkhead connector to the right, going to the battery everything looks good, going to the left, I am assuming to the HEI, starter etc is hacked all to hades. Does anyone have any pictures. Most of these wires are not original and are also spray painted black. The only thing that is not stock on this truck is the HEI. Any help getting her started again would be most appreciated. Thanks David
