If you are really on a budget go to the Pik A Part and strip the wiring harness out of a late model car. You will get enough stuff to wire about 5 hot rods (slight exaggeration) and you will not have the problems you run into when you wire a car off 1 roll of wire all one color (impossible to troubleshoot). I have done this and reused the connectors, fuse panel etc. It helps to get the stuff off the same make of car, Ford for Ford, VW for VW, GM for GM etc. Before you are done you will wish you bought the kit but, if done properly, your electrical system will be up to the same standards as a brand new car.
