The adapter plug is the key. I f you do not have it there is no way the alternator will work. the plugs on the fox must do not work, and the power plug (the big one ) is removed from the car and spliced into the new wiring. The alternator bracket mus also be modifed as well. The power wire is about 9ft long and MUST have a FUSE in line to protect the car's electrical system and the fuse must at least match the output of the alternator. Any one who knows about car audio, a 130 amp fuse is about 20 bucks on its own and it would have to have a cover over that 10-30 dollars, and don't forget all the eyelets needed to connect the system. Heat shielding is required (passes next to the radiator). You are looking at over 70 dollars just to build the power wire, and you would still need the new 3g conversion plug.
