The control box is part of the charging circuit. Additionally there is wire color code and trouble-shooting .

The snap connector for the fuel pump wire is located in the right rear corner of the engine bay.

Start checking the circuits and color codes here: Simplified Wiring Diagrams and on several pages to follow.

You can tell by the wire colors which ones connect where. The starter is not polarity sensitive, so if you reverse the battery, it can be negative earth just as well as positive earth. He also explains the specific operation of many parts. This model uses just one filament in the rear lamps for both brake light and turn signal, so it incorporates a . Now back to the diagram for ET-101e - Switch On and Fused. Everything that is not lighting circuits.
