The T-One Vehicle Wiring Harness # TK73VR is a fit for a 2022 Lexus NX 350 but as of right now (July 2023) we don't have a tee-type fitting like the TK73VR confirm to fit, but I do have an alternative with the ZCI Wiring Kit # 119250KIT.

I really like this kit, especially for newer vehicles, because it uses clamps to sense when to send power to the different trailer light signals and it pulls power directly from the vehicle battery. A lot of other universal kits will pull power from the battery as well, but they install by splicing into the OEM wiring which makes it prone to damaging the wiring. The ZCI kit is much more safe to install which is why I like it so much.

Hi Dan; this appears to be a factory issue that Tekonsha has never corrected. We have had many customers successfully install the #TK73VR as is but some have had to modify the wiring harness because it wasn't pinned correctly. This is the only…

The difference between the Class II and Class III hitches has to do with their Gross Trailer Weight (GTW), their Tongue Weight (TW), and their Hitch Receiver Size. Class II trailer hitch receivers have a 1-1/4 inch receiver and can be rated up to…
