Accessory Switch Installation Guide

Installing an accessory switch on your Harley Davidson can be a great way to add more functionality to your motorcycle. With the right preparation and appropriate service, you can easily install an accessory switch on your motorcycle. In this guide, we will walk you through the steps to install an accessory switch on your Harley Davidson.

First, you will need to ensure that the accessory switch you have is compatible with your motorcycle model fitment. You can check the service manual for your motorcycle to see if there are any specific instructions for installing an accessory switch. If you are unsure about the compatibility of the accessory switch, you can consult with an authorized Harley-Davidson dealer.

Before you begin the installation, you will need to remove the right side cover and remove the seat to access the wiring. Once you have access to the wiring, you can begin the installation process.

To install the dash panel switch, you will need to connect the accessories to either the four-way connector or the splice caps. Then, connect the stock harness connector located under the switch hole plug to the dash panel switch. Position the dash panel switch into the dash panel opening and install the two screws. Tighten the screws to 1.4-1.9 N·m (12-17 in-lbs).

If you are installing a rocker switch kit for auxiliary accessory housing, determine the desired location of the rocker switch-to accessory wire splice point(s) before cutting any wires. Allow enough slack in the wires to properly route the wires and to allow for fork movement. Trim the switch and accessory wires at the splice point, allowing approximately 1-2 in. (25.4-50.8 mm) of overlap on each wire.

Finally, test the accessory switch to make sure it is working correctly. If you encounter any issues during the installation process, consult with an authorized Harley-Davidson dealer for appropriate service.

In summary, installing an accessory switch on your Harley Davidson requires proper preparation, appropriate service, and careful installation. By following the steps outlined in this guide, you can easily install an accessory switch on your motorcycle and enjoy the added functionality it provides.

Wiring and Connection Procedures

When it comes to wiring and connecting accessories on your Harley Davidson, it is very important to follow the correct procedures to ensure safety and proper function. We will guide you through the steps to make sure that your wiring is done correctly.

First, make sure that your battery is disconnected before starting any wiring work. This will prevent any electrical shocks or damage to your bike’s electrical system. Next, locate the wire harness on your bike. This is the bundle of wires that connects all of the electrical components on your bike. Check the wiring diagram to identify the wires that you will need to connect your accessories.

Once you have identified the wires you need, you can begin connecting your electrical accessories. Make sure that you use the correct gauge wire for your accessory and that it is securely connected to the wire harness. Use cable straps to secure your wiring to the frame of your bike to prevent any damage or interference.

When connecting your accessories, it is important to use a relay or inline fuse holder to protect your bike’s electrical system in case of a short circuit. Make sure that you use ring terminals and a positive battery terminal bolt to connect your accessories to the positive terminal of your battery.

To ensure proper function, use an electrical connection harness to connect your accessories to the eight-way Molex P&A accessory connector. This will provide battery power, ignition/accessory power, and ground connection to your accessories. Make sure that you seal all of your connections with sealed splice connectors to prevent any water or moisture from entering the wiring.

Finally, install an inline fuse on your accessory’s positive wire and install the main fuse back into the fuse box. This will protect your bike’s electrical system from any overloads or short circuits. Make sure that you verify that the ignition switch is off before installing the main fuse.

In conclusion, wiring and connecting accessories on your Harley Davidson requires attention to detail and following the correct procedures. By following the steps outlined above, you can ensure that your accessories are properly connected and safe to use.
