I have wanted to find these for a while and now realize that I can't read these things. How can you tell the difference between models on here?

You have to look at the details like "premium" means LED package. Most of the drawings combine all models, then where there are differences they'll add some extra details with dashed boxes or the like.

For example, the extra wiring in the back up lamp system for diesels and/or manual transmissions

Thanks for posting this excellent collection. Should be useful for MANY projects, such as linking Auxiliary Panel-driven Driving Lights to High Beams via a relay.

One question: Do these diagrams apply to both 2018 and 2019 models? There are a number of options I viewed that I don't believe were part of the USA 2018 feature set.

Thanks!

(Looks like this is "stickied" in multiple places, rather than forwarded/linked from multiple locations. To keep replies in one thread, I suggest the use of forwarding links. I just posted this question in Lighting, copying here since the OP has been responding in this thread: )

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"

This is awesome! Thank you!! In looking into some of the lighting info (like DRL-LEFT) there's a "base" or "Premium" and I see there are different pinouts between them. When looking at detail of either of these the diagrams it says "driver" when referring to the lamps. The term "driver" is normally called out when referring to LED lighting. I think I've seen posts where they say their harnesses look different between LED verses non-LED. Anyone know? I will be diving into my fender lights (non LED) over the next couple of days as I add Oracle Halos to my headlights. I will be comparing to this diagram. I'm sure there will be many posts on this. Thanks again.

Amazing. Is there a way to find where exactly these wire are in the Jeep and where they terminate?. Some of course are obvious and labeling is descriptive enough but some are not. I'm trying to track down the Power top power wires. I "think" they terminate in the block of wires in the back in the rear cargo. Has anyone done a breakdown of all the wires in that block? Since I dont have a power top, these could be used for a fridge instead for example.

Is there also a key to what the lables are. Some are easy like RD=Red. But what do the numbers mean like 9 in the pic.

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.
