The manual is not the best at showing these locations because they normally just reuse drawings from other vehicles so they cut down on publishing costs. Which means they are not going to include this level of detail.

However, they are normally in the same general location which will be towards the bottom of the firewall and on the passenger side just on the other side of the HVAC housing.

Here is a video that talks about this exact issue which will help:

Below are the diagrams from the manual that will help with the location. Keep in mind, these may look slightly different but they should be close.

Let us know if you have other questions on this.

Thanks
