Tekonsha confirms that the correct T-One wiring harness for a 2018 Wrangler Unlimited JL is part # 118786.

The # 118416 harness you'd looked at is a fit for the JK model, and wouldn't work with your JL, as 2018 was a split model year for the Wrangler where Jeep produced both the first model year of the JL and the final model year of the JK.

I've linked to an installation video for you.
