This is not necessarily a guide for anything, but more of an information post that gathers information that is here in the forums and from information from first and second edition service manuals.
Alternator Wiring
Sense: This wire helps the alternator to maintain proper and steady voltage. This gets connected to any remote (12volt constant) location. Some people have tagged this wire to the starter post or fuse box, but any 12V location should be fine. (mine is on a switch)
Ignition: This wire Goes to switched ignition. This wire will only get 12V when the car is on. The purpose of this wire to charge the field winding's. any loaction that only has 12v when the car is on will work. (mine is on a switch)
Lamp: This wire tells us when there is a problem with our alternators, and gets connected to the negative side of a warning lamp. the alternator outputs a ground when its not charging, and outputs 12V when it is. (mine is hooked to (-) on a led)
FR: If anyone has info on this wire, please pm me. From what i can tell is it runs to the ECU on the fuel injected models. Members have reported that the car functions properly without any check lights without it.

Since the FR wire isnt vital to the cars operation, this allows fuel injected and carbd alternators to be interchangeable.
79-83 Toyota pickup Alternators can be modified to work on our A series motors. the external dimensions are the same, but you will have to run an external voltage regulator (easy to find online).
A little more about the Lamp wire since i didnt go into it.... The lamp wire gets connected to the negative side of your charge light or an led . The positive side of the led gets connected to something with switch power. factory it gets the 12v from the Ignition wire.
