Need Help with 2014 JBL Entune wiring

Let me start by saying I've already spent HOURS searching and researching here. I've downloaded a ton of diagrams and helpful information from other posts but I still need some help.

I'm attempting to put a 2014 JBL Entune radio into a 2010 JBL equipped truck. The problem I'm running into is that the 2014 radio I have doesn't seem to have the same JBL connector as every other JBL radio I've seen. (Face of my radio says JBL on it and the VIN from the truck confirms it originally came equipped with the JBL system.)

Here is the back of my 2010 JBL radio. I've boxed the JBL connection - in pretty much every post I've seen ALL JBL radios have used this connection style regardless of year.



Here is the back of my 2014 JBL Entune. It appears to have the standard speaker wiring plug that I've seen on all of the non-JBL radios.



Below is a shot of the truck-side of my JBL wiring harness. This plug originally plugged directly into the back of the radio. I've identified what each wire is for, I just need to know which pins in the above pic each should be wired to. (Note, it's hard to see, but, in the pic the connector is plugged into an adapter I'll be using to make the connection.)



I believe I have all of the wiring harnesses/adapters I need to make the connections but I'm just unsure of which wires go where for the JBL wiring. I've found wiring diagrams for 2012, 2013, 2014 and 2015 models but all the documentation I have shows the pinouts for the connection style on my 2010. I cannot find a pinout for the connector that I'm finding on my 2014 JBL unit. (Also of note... The connection style on my 2014 is the same as is found on many non-JBL units. I have the pinouts for this connector when used on non-JBL radios and of course this is not useful. I need the pinout for when this connector is found on a JBL radio).

Has anyone run into this? Any help would be greatly appreciated - Thanks!

 

Man, nothing? I must have some odd-ball stereo here cause I know many others have done similar conversions. BUMP

 

Can't remember which wires go where but i know that two wires from the 28 pin connection go to the 14 plug to turn on amp. It been a long time so don't remember and i followed 14 diagram to to see which wires go from one plug to the other plug.

 

PM incoming

 

Any chance you have the wiring diagrams you used to figure it out? I'm getting closer but still running into road blocks. I thought the 20+8 to 28 pin adapter was going to be separate from the other harness I needed to make for the JBL connections. But... now I'm seeing there's some crossover that needs to be done (as it sounds like you're saying).

I think I have most of it figured out, except:

• 2014 has INT+ and INT- wires which I can't find counterparts for on the 2010. But, I only have a pre-bluetooth wiring diagram from 07 so I think that might be the issue. INT appears to be related to Bluetooth related so I'm thinking there are Bluetooth wires from the 2010 20 pin or 8 pin connector that need to be brought over.
• 2010 has ILL+ and ILL- wires which I can't find counterparts for on the 2014.
• 2014 has two green wires (or maybe a GRN and GRN/WHT) that I can't identify. I cannot find them on the 2015 wiring diagram I have. I'm wondering if these are the counterparts to the ILL wires from the 2010. Their position in the 2014 pinout makes me think that's wha they are.
• There's an "Ignition" wire on the 2014 which I can't find a counterpart for on the 2010 wiring. I may just tap into the ACC wire from the 2010 and connect that to the ACC and IGN pins on the 2014.

 

Sorry I checked my computer and everything is gone. On the 10 the 2 wires are on the 10 plug on the 14 they go to the 28 plug can't remember which wires sorry!

TX- and TX+ are the 2 wires maybe red-white and orange

 

Thanks for at least looking for me. I'll give my ideas a try and hope for the best!

 

So far, so good. I'm hoping I can find the time to put up another thread full of info for the next guy... but until then a quick recap.

1. INT +/- wires on the 2014 were left disconnected. I couldn't find an obvious set of wires to connect these to from my 2010 wiring. So far everything seems to be working so I'm not sure what these wires are for.
2. Mute. I didn't have an extra wire on the Toyota 20+8 to 28 pin adapter so I didn't bother adding this yet. So, I know where the Mute wires are for 2010 and 2014 but just don't have a good way to make the connection. But, so far everything is working as far as I can tell.
3. ILL +/- were obvious on the 2010 but I was unsure on the 2014. But, I confirmed that the GRN (B10) and GRN/WHT (A5) wires are in fact the ILL+ and ILL- (respectively) wires. Hooked these up and illumination now works.
4. TX +/- wires needed to be run from the "JBL" adapter harness over to the 20+8 to 28 pin adapter. These wires may have other functions but I think they work to turn on the JBL system. Before I had these hooked up there was no sound at all through the speakers.

I've got it installed now temporarily until I get the trim/surround I need to install fully. This will also give me time to test out what is and is not working. So far everything works except the stuff I didn't hook up like NAV and Satellite radio. Also, when I hit the "mode" button on the steering wheel the radio froze and needed a reset. I haven't tested the BT buttons on the steering wheel yet.

 

Congrats on your project!
Mine is almost identical but I need help to find the wiring diagram of the connectors shown:
Photo attached shows the difference between my non JBL radio (original, 2015 Prius Plug in) and a JBL head unit (upgrade, taken from 2015 Prius).
I want to install the JBL unit but I need the wiring diagram of both connectors, the non JBL and the JBL head units in order to make a harness.
Thanks!

 

JBL won’t work in a non JBL. Non JBL has a built in amp JBL doesn’t that why they have one behind the rear seat and different wiring

 

Yup. @galileofigaro @moonman50 is correct. The JBL head unit has no internal amplifier so it's not capable of sending sound to your speakers. You would also need to install a corresponding JBL amplifier - which is a much bigger job than swapping the head units. It's been done before here but it's not something I'd consider worthwhile.

The JBL equipped vehicles do not have better sound because of the head unit. The reason the JBL sound systems are better is because the speakers are better, they have a subwoofer and a dedicated amplifier which produces more power than the non-JBL internal amplifier. The head unit itself is not an upgrade.

Having the non-JBL stereo is actually a little bit of an advantage if you want to upgrade with aftermarket stereo equipment. You can pretty easily keep your stock stereo and add new door speakers, a small amp to power them and a small powered subwoofer. This would be relatively affordable and would make for a great stereo. Trying to do that with the JBL equipped vehicles is a bit more of a challenge and requires some add-on items to get it to work.

 

I’ll 3rd the two above posts.
JBL won’t go in non-JBL

 

Awesome!

 

Actually... its just four bolts and few plugs goes in easily.

Kidding! This has actually intrigued me for awhile so I bought a Nav/JBL headunit off Ebay out of a Sequoia for $100 (mint!) and set to work.
In my quest I came up with three ways to make JBL head unit work in a non JBL equipped truck, starting from hardest to easiest.

- The system particularly on 2013-2017 trucks uses a feedback loop, meaning that a signal is sent to the amp where it is processed then sent out to the speakers and woofer. This is where you would need to create a false signal to make head unit think it is actually working with an amp (assuming you don't have one). This false feedback requires tapping into one of the outputs on the r29/r30 (depending on cab configuration) plug and running it into spot 1/7/3/8 on the J17 plug. Honestly I played around with this idea for awhile just wasn't impressed as the sound was extremely grainy also slightly electrocuted myself.

- If you read all the forums on this swap everyone is convinced that 2013 and up head units don't have a built in amp well that is false, they do however they are not adjustable i.e volume/fade/balance you can override this feature by de-soldering the extra Panasonic chip on the main mother board for the radio <- (This is key word as there are four main circuits boards in the unit). Afterwards you'll need to re-solder a jumper from front to back this completes the circuits and makes the radio act as a stand alone unit allowing for adjustment.

- Of course the easiest requires two head units, if you already have the Entune Audio Plus system your golden if not you'll need to source one. Both main radio circuit boards are identical except for the aforementioned processor chip (the magic in the JBL system is not the head unit its the amp) by swapping the two boards you still maintain all of the digital JBL features, Navigation and Entune app suite which are on a separate circuit boards with the ability to run an amp straight off the J17 plug.

Attached below is the schematics I used, will post photos whenever I get them off my camera.

 

Hey sarge, So I have an entune head unit i'm trying to put in a 2010 4Runner and some of the plugs go in fine, it turns on, I have static (no antenna hooked up, need an adapter) and can't connect bluetooth cuz it says no mic connected... you seem to be quite skilled at getting schematics. I'm hoping to find them so i can figure out which plugs have Mic, back up cam, etc. and make plugs that fit the new head unit.

If you have any ideas I'd love some help. Thank You.

 

Hello my wiring is the same but mine is for a 2009 Tacoma with the job head unit and I am trying to figure out what wire is what due to the connector being cut out
