Things You'll Need
10-gauge automotive wire
14-gauge automotive wire
Replacement alternator connecting plug
Soldering gun
Solder
Terminals
Heat shrink tubing

Instructions
1
Disconnect the vehicle battery.

2
Insert the replacement alternator plug into the receptacle on the rear side of the alternator.

3
Cut a short piece of heat shrink tubing and slide it on the pigtail from terminal number 1 on the new alternator plug.

4
Connect a 14-gauge wire to the pigtail and solder in place. Cover with the heat shrink tubing, which can now be heated and shrunk to insulate the connection. Connect the other end of the 14-gauge wire to the IGN or ACC terminal of the ignition switch.

5
Splice a 10-gauge wire to the number 2 pigtail on the alternator plug and insulate with heat shrink tubing. The other end of this wire can be connected to the same place on the starter solenoid as the battery positive cable, or, in the case of a remotely mounted battery, to the positive terminal at the battery. This wire is the voltage-sensing wire, so connection at or near the battery is best.

6
Cut another length of 10-gauge wire and connect to the voltage output stud on the back of the alternator and the starter solenoid. Connect to the same stud on the solenoid as the battery positive cable.

7
Reconnect the vehicle battery.
