Routing Power Wire Through Firewall on 2021 Toyota Highlander

Question

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.

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.
