Bumping for Thursday! Anyone know a site I can pay for the access the wiring diagrams for a 2016 Tucson?

Also, do any of you know the proper way to set up the line out converter? I bought a rockford fosgate class D single channel amp... Do I only need to splice into one rear speaker for the rca output?? Also, other than adjusting the gain and whatnot, is there anything else I need to do with the LOC? Thanks a lot

I used it for my trailer wiring harness and it worked flawlessly.

follow the link at your own risk.
I also have the problem with the firewall passthrough. It seems that the RHD Tucson have a different arrangement. See attached pictures:

(a) Pic_1 shows the overview of the engine compartment - Battery, Air Filter and Fuse box on the right. The steering wheel would be in the upper left.
(b) Pic_2 is a gradual zoom in on the right hand side showing the Air Filter and just behind that is some pipes and the first potential firewall entry point.
(c) Pic_3 is close up of the first firewall entry shown in pic 2. This will come in on the glove box side behind the air bag. Its not visible from the footwell, or behind the glove box.
(d) Pic_4 is next two potential firewall entry points just to the left of the one in Pic 3.
(e) Pic_5 is a another view of of Pic 4
(f) Pic_6 that wire that I am holding is the hood release wire - it goes into the firewall somewhere behind that fluid container. I can barely feel back there much less feed a wire through that part.
(g) Pic_7 shows the driver side footwell where the hood release cable and alarm cable come into the cabin.

I am not sure which one of the ones that I have show matches the one used by Navein - I suspect it is the one show in Pic_3 as the most promising. I have two issues - first if I unscrew the plastic cover - are the bolts locked in posiition so I can tight back the nuts? The other issue is where it comes out in the cabin. Even with the deck removed, I am not sure I can see the entry point like how Navein has shown.

The only other option is to use the one suggested by Tucson_Tony. there are two issues- (1) Pushing the cable in from the engine side is going to be hard because of accessibility. I could try to push from the cabin out but I don't know how successful. The second is spacing - the first cable is for a front camera but I will also need space for two front sensor wires as well. I don't think there is sufficient space for those as well.

Any suggestions?

Thanks.

Then below all the panels to the back by the spare tyre.

Also here are the wiring diagrams for the 8" Navigation with premium audio


as well as the regular 6 speaker head unit set up (ie no stock amplifier)


Also if you need more information, you can head over to this thread "Adding Subwoofer to factory location?" started by gggplaya if you need more info. A few of us including gggplaya, Tucson Tony and myself partially documented our installs on that thread.

Hey Jason_R28,

I just realized looking at your posting that you were the other Trini - Thanks for the pictures - I was tracing the pass through to get the cable using your suggestion of going through the door grommet but stubbornly was looking at the drivers side because the left side I have to somehow pass it behind the glove box and the passenger side airbag. However the driver side grommet comes through behind the drivers side panel where the hood release handle is located and I have no clue how to get that bloody hood release handle off. Have you ever taken the handle off?

I may end up going up through the side you suggested, how did you make a hole in that grommet because it is hard to get access with the door there? Did you pull out the grommet and cut or cut in place? And did you run the cables up to the deck, because when I dropped the glove box it wasn't immediately obvious how to run the cable? Will have to check it again.

I see you also mentioned that you upgraded to the 8" OEM screen, did Massy get it for you or you sourced yourself?

Thanks again.

The handle is pretty simple to get off, just pull towards you like you're open the hood regularly then support the middle with your other hand and apply pressure horizontally and it should just pop off.



As for running cables through the grommet, I just popped it off and used a drill to make a large enough hole to pass whatever wires I needed for instance a larger hole was needed in the front passenger for my speaker wire and 4 gauge power wire.


The panel on the inside pops off and you'll have access to the cables coming through the rubber plug.


As for running wires up to the head unit. On the right hand side I have a nine wire running to my digital sound processor from the head unit and on the left hand side I have the RCA cable from my rear view camera leading up the the head unit. It's passed beneath all the trim panels and leads up to the head unit under the passenger side carpet.






Once the head unit is out you're able to clearly see where you can fish the wire up to it.


I also used the same rubber plug to run wires for my rear door speakers and into the rubber grommet.



I got the head unit from a seller I found on eBay in Ukraine because it's the unit from the SE Nav version in Europe since it's has a 4 channel output as opposed to the SPDIF output that the US/Canada NAV has. What I got was just the head unit and the front fascia for an LHD model and with some hacking up of the one I had with the radio that came with my car and LHD one I put them together. The wiring schematic was also different so I used a harness extension and remapped the wires as necessary.


Massy is as incompetent and expensive as can be. As long as it's not warranty related I try have as little interaction as possible.

So this is for those coming late into this thread and wanting to do the engine compartment to side fender route. 2hours later I was able to accomplish it. Albeit I did it with 0ga and it was just small enough to get through. I used NVX 0ga so if your brand is larger you will have extreme difficulties. The hole behind the trunk release panel. Is covered with a small piece of tape like foam just so you dont do what I did and pop out two rubber grommets( both gone somewhere) that you wont be using.
