The Throttle harness has been moved from the right side (on 2024's) to the left side for 2025 RT's. It is now under the left front speakers on top of the blower motor housing. You will need to remove the left side panels and look up for it from a very low position (I sat on the floor) with a flashlight to find it. I hope this helps you have less frustration than I did while trying to find it, because the 2024+ installation videos show it on the right side.
