Helpful Expert Reply:
Yes, you can use the Roadmaster Single Park Light Diode # RM-690 with a Hopkins Reliance brake controller on your 2018 Toyota Highlander.
The issue is the backfeeding with the Pre-Collision System (PCS) so you want to install this diode to the wire that connects to the cold side of the stop light switch (which is generally the red wire).
