I’m not sure what model that is but That looks like the driver’s side of the engine compartment.
if you’re talking about the factory auxiliary wires they’ll be wrapped up in a bundle on the passenger side on the wheelwell side if the battery

In the first picture it should be bundled around there next to battery on right side. Near where my finger is pointing. I've got a lot going on in that area.
Second picture is the area on right side of transmission hunp under the dash near bottom of picture. Taped up and tucked in possibly under carpet on side.
