Accord Euro Electrical Schematic

[ozy944]

Hi guys, apologies if this exists somewhere else on the forum.

I've just acquired (courtesy of MRGU) a cl9 satnav unit.

I'm pretty keen to start retrofitting this to my CL9 lux non-nav.


Does anyone have a service manual that contains electrical schematics? If so, would very much appreciate any advice/links/words of wisdom etc

This has to be for a Euro, not a TSX as the TSX nav unit is different with different wiring.

[Kodak]

I am almost certain you can settle for the 'accord' as sold in Europe. You can buy the cd on ebay

[ozy944]

Kodak, bit confused by your response...I already have the satnav unit...I need a wiring diagram for it to check all my wiring before I get too far ahead of myself.

And the Accord nav from europe is a no-go as its a premium sound system vs the version sold here.

[mrgu]

Oz ..I will ring Hondaworld for u to see if they have it

[ozy944]

Bump....

[Fredoops]

pretty sure it's plug and play.

[Kodak]

I meant you can buy the service manual on cd from eBay. It has all the schematics you need.

[ozy944]

The service manuals on ebay are all for the US Spec Acura TSX. This had a different sat nav unit (XM, voice activation, dvd in the boot etc).

Spoke to the Honda dealer - they'll sell me the original manual for $600, seems a bit over the top to get my hands on two pages...

[mrgu]

go and get one from the dealer here. definitely charges cheaper

[Fredoops]

Why do you need electrical charts?

Isn't te NAV a direct bolt on I the dash?

[mrgu]

It's not Fred!!!

[mrgu]

It's way more complicated than I think it would be ! Otherwise I would have kept it myself

[longers]

It wasn't too overly complicated when I did it. You do need the diagram to help you with matching the cables.

In saying that there were a few things missing.
- I haven't been able to locate the vehicle speed sensor
- I'm unsure why but I can't seem to hear the guidance voice.

Other than that it is pretty simple.
- The A/C controls go in fine.
- The head unit cable is tapped into to accomodate a few cables that run to the DVD ROM.

[mrgu]

where does dvd rom cable goto?

[longers]

I'm going to take the headunit out soon and when I do I'll take some pics to show you.

[ozy944]

Longers,

Photos would be magnificent - I'm about to start putting mine together. When you say vehicle speed sensor, I believe this is the blue wire on the dvd unit square (6 pin) plug. I can tell you where the speed sensor is but only for a US accord or TSX - not sure if it translates directly to the euro's.

Keep us posted about when you get a chance to take some photos of what you did and how.

[longers]

Yeah well I based my conversion off the schematics of a US Accord. But then again I have the wide body accord and the navigation unit was off a euro.

So I had to go by pin matching and not colour matching.

[ozy944]

So just an update...things with the non navi to navi are currently going swimmingly...great learning experience.

The one thorn in my side is how and what on earth to splice to connect to the Back LT (Multiplex integrated control switch).

Any ideas anyone?

Hooked up off board via the car battery and some fine-and-dandy alligator clips.

Screen boots with a message "no dvd disk - insert dvd..."

There used to be a guy on ebay/gumtree that sold satnav dvd's. Is said person still around on the forums?

FYI the job is not quite done....still have to make a sensible decision on vehicle speed sensor inputs, trip info and fuel consumption details, screen power, navigation drive power, more tidying up and safe wiring practice...

...plus haven't fired up the navi with everything else connected...stay tuned for tomorrow's update folks...

[longers]

nice, i see you finally got the dvd rom to sit in proper.

[ozy944]

Not quite sitting proper mate....cant get a hold of mrgu to source the missing part.

I've done some dodgy engimanearing, oversized washers to act as a spacer and doubled over on the cubby hole mount...seems to work ok....will know more tomorrow :D

[mrgu]

.cant get a hold of mrgu to source the missing part.


Cos he s in bloody china. . Lol

Oz .. Which part is missing? I watched him taking it off. Shouldn't miss any parts except for the damaged air vent clip which I will chase up when back.. Otherwise good job on fitting it mate

[ozy944]

That explains things! haha

Mate, theres another bracket that mounts the brackets attached to the dvd drive...i.e. sort of like a rectangular double DIN unit....

@ longers...reckon you've got a photo around or something to help mrgu kick some wrecker butt? :)

[ozy944]

Ladies and gents....I'm stuck :(

Faulty dvd drive. Won't eject the dvd (genuine honda dvd in drive)...powers up but doesnt spin properly....any button presses cause it to chuck skitz.

Mrgu - anything you can do with your wrecker about this?

https://lh6.googleusercontent.com/-29FgAZwgJY4/UXOR8nHwnJI/AAAAAAAAAb8/jlyDf1gH8Mo/s640/IMG_20130421_171234.JPG

[mrgu]

That's a bummer...I will definitely follow up when get back.oz

[Snoop_gee]

its good someone is having a real red HOT go at this.
THere has been so many previous posts about trying to retro fit it.

Hopefully u guys can pull it off.

[ozy944]

Thanks for the continued support gents. On the bright side, conceptually this will work on any 7th gen accord euro both pre and post facelift.

What i need is a volunteer fault finder. Someone who can plug my wiring harness into their satnav. I'm happy to pay postage both ways andi can guarantee no harm will come to your car.

This or someone lend me their DVD drive lol. I need to drill down to what exactly is the problem.

Any volunteers?

[Snoop_gee]

which state are u located in?

[ozy944]

Tasmania...though I'm up in Victoria quite often (not with the car though). Happy to post bits + instructions for anyone keen?

[ozy944]

A happy update, things back on track....final install awaits... :)

MRGU - any updates on getting those brackets from the wrecker?

[ozy944]

Stress tested for a couple of hours today...works really well! Very impressed with the gps, screen brightness, response rate etc. So glad I didnt go down the path of a dodgy aftermarket unit.

I am delaying the final installation fit-up for a week as awaiting some 20 pin connectors - I am building a harness kit such that the installation is simply plug and play (no splicing of any car wires at all :D) just in case I decide to dismantle it some day.

Lesson learnt from the 'roadblock' I previously encountered: Dont trust cheap wiring...the copper vs insulation ratio can be disturbingly bad. I've redone all of mine to ensure RF, EM shielding as well as preventing any involuntary fuse wires :D.

Also, I can confirm....the satnav mod will work on:

- All Honda Accords 03-08
- All Honda Accord Euro's 03-08
- Any other car in the world although a little bit more wiring work is required and assuming you can fit the damn thing into your center dash
- As long as you acquire all your components from a UK Spec, JDM spec, US spec, this is also retrofittable although some functions may require a little more work

Happy to help anyone else who is keen on doing this mod too - there's no need at all to go to an auto sparky and if you're clever about it, it can be entirely plug and play too.

many million thanks to Longers for testing the dvd drive for me and helping with troubleshooting!

[longers]

good work!

[mrgu]

Good job oz.. U made it! Once I purchased mine, I will definitely ask for ur expertise

[ozy944]

No problem mate ;) - yeah its not that hard really. Just take some photos of the car before you pull bits out and i can tell you what you'll need. I've still got to get the brackets that mount the dvd drive - its a dodgy install without them.

[ozy944]

Ladies and gents....its done!

Here are some photos of the final install:

Here is the connector connected to my 20 pin audio wire....note this means the mod is 100% plug and play...no splicing and no permanent mod to the car

Hi Ozy944,

Could you please details a bit where are located CAN-H, CAN-L and VSS signals ?
From the picture is not very clear.

Thank you in advance

Mate,

The ecm connections for can-h, can-l, and vss are on the farthest right ecm connector I.e. on the passenger side closest to the rear of the car.

Vss is on the bottom row and its light blue in color. It is pin no. 26 and the 5th wire from the left side.

Can H is wire location 11. It is white and the first connector on the second row from left as the first position should be empty.

Can L is wire location 24 and is red in color. It is one the bottom row I.e two to the left of vss with a gray(?) Wire in between.

You are testing my memory as I am sitting at an airport on the way to Melbourne!

The way I connected it is there is a length of the ecm harness that bends back around I.e. there is some excess length where you can expose some wire and make at junction. I built my own connector so that it is readily detached.

I can also vouch that it works perfectly fine without any ecm connections. The only loss is that fuel information is blocked out as this is what that information is used for. If you don't feel comfortable splicing, don't as you could do some damage. Also make sure you trace back the wires to the connector. It's very easy to get confused as there are 30+ wires bunched up and many of the same color.

Note also that you could connect can h and can l by pulling out the gauge cluster add they are the same source for the trip information on your gauge cluster.

Gps works very well without it.

Hope this helped and apologies for the messiness!

Ok ! Thanks a lot.
Hope you have a good flight :-).
May I ask you, if it is possible of course, to help me a bit with a more clearer picture ?
BTW: I'm from Bucharest, Romania, Europe, from the other side of the world :-)

[ozy944]

What exactly do you want a picture of mate? Do you mean photos of which wires to splice?

I'll do you one better:

Yes, I see now. Now its clear.
One more question please, something is not very clear in my mind regarding the relationship between HFT and Navi.

I saw on other forums, for instance here http://tl.acurazine.com/forums/showthread.php?t=739375, when navi it is switched in diagnose mode, in Navi System Link, there it is also displayed the HFT unit. Something like in the attached picture.

For the European version of Honda Accord this functionality it is also supported ? What do you have in your report about System Link, HFT unit it is integrated ?

Thank you very much for your answers.
Really appreciated.

I'm pretty sure this is the 'HFL' unit - i.e. Handsfree Link. EU Spec accords have the telephone controls + the ability to input voice controls into the head unit.

This is not available on the AUS Spec head unit i.e. it doesnt appear on the diagnostics screen.

Hope this helps.
