Vehicle Wiring Harness For a 2021 Toyota Sienna.

Question:

Wondering if the 119250KIT is compatible with the 2021 Toyota Sienna, as Ive seen conflicting info on the site some down menus end at 2020 this kit was recommended for 2021 Sienna in another place. Presuming it does for a moment, this looks like the kind that splices into existing wiring, as opposed to unplugging a taillight and using the C59236 and splicing in a male/female plug to connect, or using a ZCI harness. Do you know if that will have warranty implications? Would I be better off with the 119250KIT though I'd be poorer...?

Both the Curt Powered Tail Light Converter with 4-Pole Flat Trailer Connector # C59236 and the ZCI Circuit Protected Vehicle Wiring Harness # 119250KIT are universal kits that will work on most all vehicles. You can use either of these on your 2021 Toyota Sienna. These kits both use powered modules to reduce the additional power pulled through the vehicle harness. There for it will not void your warranty.

I recommend using the Tekonsha # 119250KIT as it has a tried-and-true converter reputation and why splice when you don't have to? This kit being no-splice will also not have any warranty concerns.
