You'll have to first have a look and see what is not 'factory' looking wiring. You may see splices in some of the wires. You may see a factory orange wire (for example) that has a connector then goes into another color wire. Thats probably an indication that, that wire has been cut into. You may see its 'other end' of the same color, with a similar connection, and thats probably where the starter wire was cut and connected to either a kill switch or some sort of starter disabling device. When I did my car, the starter wouldnt even turn. I pulled the starter and cleaned everything out of it, like grease etc. Put new bearings in and lubed nothing else. Its been starting perfect now for years. The lube seems to gather dust etc and turn it into a paste that sticks the solenoid and bendix gear. Its a bit of a circus to get to all the parts but once its done it works fine.
