The following wiring diagram, electrical system schematics, connectors, and pinouts apply for Jeep Wrangler TJ 2000 models. Here you will find detail information about the entire electrical system description, illustration, troubleshooting and service procedures for each system.
The wiring diagrams are grouped into individual sections. If a component is most likely found in a particular group, it will be shown complete (all wires, connectors, and pins) within that group. For example, the Auto Shutdown Relay is most likely to be found in Group 30, so it is shown there complete. It can, however, be shown partially in another group if it contains some associated wiring.
