Alternator
REMOVAL & INSTALLATION
On some models, the alternator is mounted very low on the engine. On these models, it may be necessary to remove the gravel shield and work from beneath the truck in order to gain access to the alternator. Replacing the alternator while the engine is cold is recommended. A hot engine can result in personal injury.

to Wire a Hilux Alternator follow the procedure :---
Put on protective gloves to prevent your hands from getting dirty, but also to protect you from receiving an electric shock while you disconnect the battery cables. Open the hood of the Hilux.
Isolate the electrical supply from the battery. Use a wrench to remove the negative battery cables from the negative terminal of the battery. Remove the positive battery cable form the negative terminal of the battery. The battery terminals are labeled "+" and "-" while the cables are colored red and black, meaning positive and negative respectively. Move the cables away from the battery so they don't accidentally touch the battery terminals while you wire the Hilux alternator.
Locate the four terminals on the Hilux alternator. They are labeled B (alternator output), S (voltage regulator input), L (dashboard warning system) and IG (ignition system).
Locate the four cables that attach to the Hilux alternator. They are nearby and each one is colored differently. The large red cable attaches to terminal B using a nut and bolt while the smaller cables simply use push-in connectors. Each are different sizes so you can only connect them to the correct terminal.
Use a wrench to undo the nut from the bolt on terminal B. Slide over the eyelet on the end of the large red cable. Screw the nut on the bolt and tighten using the wrench.
Select one of the remaining three wires. Systematically try to push the connector into each terminal starting with terminal S. You can only push it in one terminal so if it doesn't go into terminal S, try terminal L and then terminal IG.
Push one of the two remaining connectors into one of the two remaining terminals. It only goes into one of them. Push the last connector into the last terminal.
Use a wrench to reconnect the positive red battery cable to the positive battery terminal. Reconnect the negative black battery cable to the negative terminal of the battery. Close the hood.
