If you have a floor starter the problem has to be in the cables or ground. Check the connection on top of the starter. Check the ground cable. If it grounds to the frame than you must have a heavy gauge ground strap from the engine to the frame. When you solve that the rest should fall in. I,ve seen those 1 color wireing jobs. Sounds like you are going to need a whole harness.
