This is what I thought / feared - anyone know if there is a wiring harness out there - would love to see a write up like this done for the JL (assume the jk / jl harnesses are not same?)
Hmmm. Interesting. It just popped up on Quadratec too (A bit pricier, of course). Going with that and a decent shallow double din radio could get close to the price of the 8.4" OEM unit, but would definitely stand out as different.
poking around my JL harness it does not match the 17JK in the link above.
You will need to buy a new sun sensor because the one you have doesn't have the 2 additional pins needed for automatic a/c sun load detection. That also means you will need to route 2 wires to connector 2 of the HVAC module. As for the in-cabin temp sensor, you will need to purchase the sensor itself as well as make the wiring harness needed for it to work, since there isn't a Mopar replacement harness for it.
There is no use in adding the additional duct temp sensors, since those will only be beneficial in a dual-zone setup. These sensors actually go into the air distribution box and not the actual ducts, meaning that you cannot buy the sensors apart and install them; they come installed when you buy a new air box. The air distribution box your JL has is the one for the single-zone a/c, meaning it's missing another blend door as well as the layout to support dual-zone functionality, even though the wiring diagram says you have 2 blend doors, you do not.
The HVAC module is located beneath the steering column to the right. You need to take off the trim piece underneath the steering wheel and then move the front driver seat all the way back.
That's interesting.. from the looks of it, all of the wires you need are already in the C2 connector, even though your Jeep doesn't have the in-cabin sensor or HVAC sun sensor. That would have to mean there should be a connector for the in-cabin sensor somewhere in there that isn't connected to anything (don't quote me on that). Also, I would check to see that your current sun sensor harness has all 4 wires on it, which would simplify the install.
Well, I'm gonna have to make a note on that. This simplifies things greatly for Sport S JLs (at least 2020s). You would only need to buy the in-cabin temp sensor and the new sun sensor, plug them in, and you should be good to go!@danny01 well I have a 20 JL sport - maybe they got smart and have only one harness now? In any case I think i only need to connect in cabin temp sensor the this connector as the sun sensor has all four wires that match the c2
tomorrow when my in cabin temp sensor arrives, I’ll let you know if my 2020 JL Sport 7” uconnect upgrade with auto temp control is working properly. Check your harness for the c2 connector in hvac module - if you have a c2 with all 6 wires you likely have a temp sponsor connector (behind right knee panel) and sun sensor - if not you’re going to need to build that c2 harness
Yeah I saw your threads and was thinking that I am having the same problems too. However I know I am not the only one that bought the infotainment climate control so was wondering if anyone elses have the same problem.
