Brake controller prewiring?

[Overland Toy]

Does anybody know if these 4 runners have pre-wired for brake controller? on my Tacoma there was a wire harness under the dash that was pre-wired and I just plugged in my prodigy ll brake controller right into. I’m not sure I’m finding any information on 26 four runners.

If you don’t have the Tow Tech Package, no.

They are prewired. See thread attached. Install looks pretty simple but it does not integrate w/ Toyota system.

Yes very informative thread.

Here is what you can find on page 212 of the owner’s manual to confirm wiring.

look into the oem trailer brake controller. It may integrate with the infotainment.

My new 2026 4Runner TRD Off Road Premium should be prewired with trailer brake controller connection because it has the tow package (4 way, 7 way), but accessing it is my challenge. The manual page above shows where it's located, but it looks like I have to remove several pieces of dash on the driver side. I am not very mechanical and nervous about pulling off dash pieces.
