Tech Tip Episode

Some information in this video is out of date, such as the number of different harness converters we offer for each manufacturer.


  • Turns aftermarket signals into a "plug and play" installation
  • OEM Yamaha style plugs terminate in female bullet connectors
  • Guaranteed to work with TST brand turn signals
  • Can be used with other aftermarket turn signals with compatible male bullet connectors


Want to upgrade the front turn signals on your Yamaha but don't want to cut or splice your motorcycle's OEM wire harness? We've got you covered with our TST Front Signal Plug 3-3 Harness Converters. Instead of wasting time with a custom wiring job and risking damage to your OEM wire harness, these Yamaha 3-3 harness converters give you the ease of a plug and play installation. They incorporate the Yamaha 3-pin connector on one end with a female bullet connector on the other. Simply plug your applicable turn signal into this harness adapter and then mate that setup to your Yamaha’s OEM connector. Wiring job done.

NOTE: Our converters come with three wires; however, if your signals only utilize two, simply leave the extra unattached.

Q: What do signal plug converters do?
A: They simply allow for a plug and play installation of your turn signals. If you intend to use these along with the TST Industries brand signals, the fit between the signals and converter is guaranteed.

Q: Do these converters give me running lights?
A: If the signals you are installing do not have a running light function, the 3-3 harness converters will not generate that feature. If the signals do support a running light, these 3-3 converters enable that feature to function properly.

Q: How long will it take for me to receive this once I order it?
A: Our handling time is 1-2 business days, and the shipping time varies based on the shipping method selected. To learn more about shipping times, please see the articles in our Terms & Conditions regarding domestic and international shipping here.

Q: I'm located outside of the United States. Will I have to pay duties on this item?
A: Some countries charge additional fees when a package is imported and delivered to the recipient. We have no way of knowing or estimating what these fees will be. It is the buyer's responsibility to cover these additional costs.

Q: What is your return and warranty policy?
A: Please read over our policies thoroughly on our terms and conditions page BEFORE making your purchase.
