I did not find the Multiple Dash switches and Aux switches.

Awesome! My only wish was you stuck the "DOWNLOAD ALL" zip file at the top of the post. I was half way thru downloading them individually before I seen this.

Good idea, I made the change, thanks!

Look at the upfitters diagram

That 9 indicates the pin number of a connector. In the "Entire-Vehicle-Connector-Map" there's a legend, a little helpful. And that same diagram, will give you a general idea of where/how the wires are routed through the jeep.

Ah. Got it. Thank you. You rock for publishing it.

Any idea what the circle labele S2901 on the brake diagram is?

Maybe that’s where the loom passes from the engine bay to inside the tub?

I have been examining the wiring diagrams linked in this thread and comparing to my '18 Sport S 2Dr. It seems that the diagrams are either specific to a model or an aggregate of all the wiring and options in all models. For example, the Blind Spot Monitor System (BSM) diagram shows a Lamp Turn Indicator in the mirror as a separate lamp from the yellow triangle BSM lamp. My vehicle does not have turn signal lamps in the mirrors and does have the BSM lamps. Are there turn signal indicator lamps in other models of the Wrangler? Are the diagrams specific to a model or have wiring for all models? Any clarification would help. Thanks.

Like you said it's an aggregate of all models. You have to read into the details, makes it kind of confusing.

I actually don't know of any Wrangler model that has a turn indicator light in the mirrors. I have also noticed that the diagrams can also include wiring for options not actually offered in the Wrangler, e.g. front bumper proximity sensors in the top level diagram

Thanks for the clarification. It is a bit of detective work but the diagrams are quite helpful.

I pulled this off TechAuthority under 2018 JL, but it's not to say that these diagrams have features from future releases or even other FCA models, e.g. the front bumper park sensors that show up in the "Entire-Vehicle-Connector-Map"

I have a Sahara JLU, I'm willing to buy stock alpine from oemmoparparts, is it prewired already and just need to install and connect?
