1992 Harley Davidson Softail Wiring Diagram

The 1992 Harley Davidson Softail wiring diagram is a valuable resource for anyone who wants to work on their bike. It shows the location of all of the electrical components on the bike, as well as the connections between them. This information can be helpful for troubleshooting electrical problems, or for making modifications to the bike's electrical system. The wiring diagram is divided into two sections: the main harness and the accessory harness. The main harness is the larger of the two, and it contains the wiring for the bike's essential systems, such as the ignition, lights, and fuel injection. The accessory harness is smaller, and it contains the wiring for the bike's optional accessories, such as the radio and heated grips. The wiring diagram is a complex document, but it is important to understand how it works in order to work on your bike safely. By understanding the wiring diagram, you can avoid making mistakes that could damage your bike or injure yourself. ### Main Harness The main harness is located under the seat of the bike. It is a black, plastic-coated wire loom that contains the following wires: *

Battery positive:

This wire connects the battery to the starter solenoid. *

Battery negative:

This wire connects the battery to the ground. *

Ignition switch:

Starter solenoid:

Radio:

This wire connects the radio to the battery. *

Heated grips:

This wire connects the heated grips to the battery. *

Other accessories:

This wire connects other optional accessories to the battery. ### Understanding the Wiring Diagram The wiring diagram is a valuable tool for anyone who wants to work on their bike. By understanding how it works, you can avoid making mistakes that could damage your bike or injure yourself. The wiring diagram is divided into two sections: the main harness and the accessory harness. The main harness is the larger of the two, and it contains the wiring for the bike's essential systems, such as the ignition, lights, and fuel injection. The accessory harness is smaller, and it contains the wiring for the bike's optional accessories, such as the radio and heated grips. Each wire in the wiring diagram is labeled with a letter and a number. The letter represents the type of wire, and the number represents the wire's function. For example, a wire labeled "B1" is a battery positive wire, and a wire labeled "L1" is a light wire. The wiring diagram also shows the color of each wire. This can be helpful for identifying wires that are difficult to see. ### Troubleshooting Electrical Problems If you are having an electrical problem with your bike, the wiring diagram can be a valuable tool for troubleshooting. By following the wiring diagram, you can trace the problem to its source and fix it. To troubleshoot an electrical problem, start by identifying the symptoms. Is the bike not starting? Are the lights not working? Are the turn signals not working? Once you have identified the symptoms, you can start tracing the problem through the wiring diagram. Follow the wires from the component that is not working back to the source. If you find a broken or disconnected wire, you can fix it by splicing in a new wire. If you cannot find a broken or disconnected wire, you may need to take your bike to a qualified mechanic for further diagnosis. ### Making Modifications to the Electrical System If you want to make modifications to the electrical system on your bike, the wiring diagram can be a valuable tool. By following the wiring diagram, you can make sure that you are connecting the new components correctly. When making modifications to the electrical system, it is important to be careful not to damage any of the existing wires. If you are not sure how to make the modifications, it is best to take your bike to a qualified mechanic. ### Conclusion The 1992 Harley Davidson Softail wiring diagram is a valuable resource for anyone who wants to work on their bike.
