wiring ?

Ive bought a wiring nite mare. Its a 91 escort dirt race car, THe wiring is cut up. All I want to do make start and run, so does any one have any ideas? All I need to wire is the computer to make the crank trigger work and injectors. I can wire the alt to work and ill put the start on a push button. and the fuel pump on a toggle switch. if anyone could help it would be good.

well.. not knowing how it has been modified, it is a bit difficult to give you any suggestions.

Maybe just get yourself a diagram and start piecing things together.
