Perfect for my ‘23 Tacoma…plugs right in to the factory plug then piggyback the factory one back into it.

Purchased for the opt7 led light strip for 2017 Tacoma. All plug and play minus the reverse wire that needs to be connected to the reverse tail light.

Used this wiring harness to install the 60 inch triple row light bar. The harness was simple to use and made the install look super clean and wire free. I would absolutely recommend it

Use this for my rear led light. Seems nice, only issue was the part that need to be pushed in was too tight, was hard to push in and if I need to remove it at sometime it's going to be very difficult.
