jay, if all of the bolts are out then the starter pinion may be stuck a little force is required dont forget it is the old one right
not sure about the wires mate normaly there are as many on new as old[live from battery,live from /to ignition switch three i count?[sometimes there is a bolt which runs behind the starter
between the starter an the engine normally three bolts]
good luck m8
