Routing Power Wire Through Firewall on 2021 Toyota Highlander
Question:
I cannot find a way to pass the power wire through the firewall of a 2021 Toyota Highlander gas model, not hybrid version. I see no open grommets, what is the best way through the firewall to get power directly from the battery.

Expert Reply:
You will want to select the grommet around the steering column and feed through that. The correct Tekonsha OEM Replacement Vehicle Wiring Harness w Brake Controller Adapter for a 2021 Toyota Highlander is # TK57VR.
Please note the linked installation video.
