Which wiring harness should I use?Updated 15 days ago

Whenever possible, we recommend using the 5-Pin wiring harness, which can be installed through your dome light cavity. (This is available in the newest generation 4Runner, bZ4X, Prius Prime, Sequoia, Tacoma, and Tundra).

If your vehicle is not compatible with the 5-Pin harness, you should install through the rearview mirror using either the 10-Pin or 12-Pin harness. Most new Toyota and Lexus vehicles are compatible with the 10-Pin harness. The 12-Pin harness is for use with 3rd gen Tacomas and some other older models. The 12-Pin harness is never to be used with the Safety Sense 12-Pin harness.
