Starts at step 21:
21. Remove the F wire from the generator and fold it back onto the wiring harness
22. Remove the F wire from the voltage regulator and fold it back onto the wiring harness
23. Connect the 2 wires left on the voltage regulator to each other using a nut and bolt and make sure they are insulated with electrical tape. You can splice them together, but then it will be harder to return it to original.
24. Remove the voltage regulator from the firewall
25. Remove the Generator and the lower generator bracket from the motor (my kit came with a new upper alternator bracket that was superfluous.)
26. Plug the DA connector into the alternator.
27. Disconnect the wire from the A post on the generator and connect it to the BAT post on the alternator along with the red DA plug wire.
28. Run the white or yellow DA plug back through the firewall to the ignition switch and hook it up to the IGN post.
29. Use black electrical tape to wrap the harness where the ugly white or yellow wire runs through the firewall and cover up the F wire from the generator
30. Connect the battery and you are done.
