Expert Reply:
No, you do not Jeff. The Redarc Tow-Pro Trail Brake Controller w/ Custom Harness item # RED74UR is a plug and play setup for your 2022 Toyota 4Runner. It already has the necessary wiring and diodes so the item # RED34FR diode is not needed.
What kind of trailer are you pulling?

I will pull a neo, rough rider, snow bear, and maybe some others. I need it to be a universal fit! :)
