These are available at the following links... HONDA CRF300L / CRF450RL LED TURN SIGNAL KIT INSTALL: The instructions below provide a high level overview of what it takes to install the front LED turn signal kit on your 2021+ Honda CRF300L or 2019+ Honda CRF450RL. This guide can be used to install both the DRC and Motogadget LED turn signals... NOTE: Please make sure your ignition is off when you are working with turn signal wiring on the bike, otherwise you could blow a fuse. 1. Remove stock front headlight shroud to get to the front turn signal wiring harness. 2. Remove the stock front turn signals, following the wiring for each turn signal to where they plug into the harness on the bike under the headlight shroud. Pay special attention to how the wiring is run, that way you can run the new LED turn signal wiring the same way, and also pay attention to how the wiring harness was packaged under the shroud, that way when you are finished with the wiring, you can put everything back the way it was with the stock turn signals. When you unplug each stock turn signal, mark the connector plugs on the bike "left" and "right" so that you know which is which when you go to plug in the new LED turn signals. 3. The Running Light Adapters (RLA) included in the kit will be wired in-line between the front turn signal harness on the bike and the new front LED's. One end of the RLA already has the OEM connector plugs pre-installed, those plug into the harness on the bike where the stock turn signals used to be plugged into. The other end of the RLA has female crimp connectors pre-installed. These will be connected to the new LED turn signals you are installing, which you will do in one of the next steps. 4. Before connecting the new LED turn signals to the RLA's, you want to mount the LED turn signals to the stock turn signal mounts, using the black plastic turn signal mounting plates included with the kit. Run the LED turn signal wiring the same way the stock turn signal wiring was run, back to the wiring harness where the RLA is plugged in. 5. After you've run the wiring back to the RLA, you may need to trim excess wire off the turn signal wires since some LED wiring can be extra long. Once you do that, you are ready to connect the LED wires to the RLA. Depending on what LED turn signals you have purchased, there are a variety of ways you can connect their wires to the RLA wires. As mentioned, the RLA's come with female bullet crimp connectors pre-installed, so if you have male crimp connectors like are typically included with DRC LED turn signals, you will want to install those on the LED wires, then clip them together with the RLA's. If you don't want to use bullet crimp connectors, you can snip those off the RLA's and use other connectors like Butt connectors, or some or our customers have even soldered the wires together for a more permanent connection. And some LED's, like Motogadgets, will include their own special connectors that you can use. Make sure you connect ground to ground and power to power (generally the ground wires are black). 6. Once you have everything connected, and before you button everything up and re-install the headlight shroud, test that the new LED turn signals function properly. Turn the ignition on and make sure the new LED's come on as running lights. Next, test that the correct turn signal flashes, both the left and right side. Also make sure your tail light and brake light still function properly. Start the bike and do the same checks. 7. If everything is working properly, you can put everything back together by packaging the wiring under the headlight shroud in a similar way to the stock turn signal wiring was packaged. Re-install the headlight shroud, and you're ready to ride! NOTE: We recommend always checking to make sure your turn signals and brake light are working properly before you leave on a ride. This should be part of every riders pre-ride checklist. |
