The 4Runner has all the wiring for towing including the 7-pin connector in the back.
The 4Runner does not have a built-in brake controller, but does have the wiring for it. Under the dash above the parking brake is a white connector for the brake controller. I installed a Tekonsha P3, but there are other good controllers. Tekonsha makes a 3040-P, which is a wiring harness that mates with Toyota's brake controller plug and Tekonsha brake controllers, so if you use that, it's just plug and play. Alternatively, you can use crimp connectors to join the connector that came in the glove box and the connector that comes with the brake controller.
Most folk mount the brake controller underdash above the parking brake. This is possible with the 4Runner, but there is a knee airbag, so your mount must avoid that. Since I have long legs, I decided to mount the brake controller in the center console, see below picture. It turned out that the 3040-P isn't long enough to reach, so I had to make my own connector anyway.
Our 4Runner came with Dunlop AT20 Grandtrek tires. Tires typically have a chart that gives the load it will carry for a given tire pressure. At 35psi, AT20's each handle 2535lb and greater pressure doesn't increase the rated load, so that's the tire pressure I use.
I also installed a ScanGauge with a BlendMount to monitor transmission temperature, see picture below. I had some trepidation about running the cable up the A pillar with curtain airbags, but it was surprisingly easy. The SRS airbag label marks a cap that just flips open, and removing the bolt underneath removes the A-pillar trim. I really like the over-the-mirror mount, but there are other good mounting places.
I also installed a monitor for a rear-view camera mounted on the back of the Escape. It's a wired connection that we've been very happy with, but it was a job to bury the wire from the back bumper to the center console.
As previously mentioned, I also installed a Long 4589 transmission cooler.
