MY10 Odyssey stereo loom colour coding help required please.

Hi everyone.

Does anyone know which wire here does what?

I'm about to pop my Clarion head unit into my Odyssey Lux (2010 model).

I need main 12V, Acc, Earth, and the illumination (dimmer for when the head lights are on) wires.

And because the aerial wire in the car is different to the older style coaxial plug, does anyone know which wire is which for the radio aerial (shield and inner signal wire)?

Thanks for the help guys.

Not offhand, but unless anyone else chimes in with a diagram, a test light will tell you in 5 mins. Hook it to the door striker or anywhere on the chassis, once you've found 12v constant, you can use that to find ground.

Thanks. All good. I'm sure I could work it out that way.

What about the aerial though?
Which wire does what?

Cheers

You could get something like this to save you from cutting up your old one.

If your set on cutting it, it should be a coax cable(unless new cars use something different) so inner most wire is signal then outer is shielding, also appears your power anntenna wire is in this plug/cable so that may need to be connected to the new harness.

from the JDM Alpine website:

I need main 12V, Acc, Earth, and the illumination (dimmer for when the head lights are on) wires.

13 yellow is power, 1 brown is earth, 23 purple is Acc, 24 grey is illumination.

IMPORTANT: the Alpine diagram is left to right to the first pic you posted.

Philip, once again you have proved your worth!

Thanks very much.

And tbM, I was just going to fit a standard coaxial plug.
I'll get one of those adaptors though and use that instead.
I think the blue wire will be unused though because the Odyssey has no electric antenna (its laminated to the rear window instead).

Cheers for your help too.

No worries, The power annetna wire can also be used to power a signal booster in some cars so even if you dont have a motorised antenna it is still sometimes needed to power the booster, if you find your not getting good reception that may be the cause so i would try connecting it in that case.

Do you know where the blue wire is supposed to be connected to?
The head unit somewhere?
Some other wire in the car somewhere?
Does it just carry 12V?

Most cars I've ever worked with have the aerial plug wired straight to the aerial.

Cheers.

Ok, the blue wire carries a 12V signal from the head unit to the antenna booster (hidden somewhere in the car), so that when the radio is on, the booster switches on.
I just have to connect it to the matching blue antenna power lead coming out of the back of my Clarion head unit.

Can't wait to show you guys what I'm doing...
The A pillars are out and in the process of being fibreglassed for some speakers,
The doors are being sound deadened and sealed and some custom speaker spacers made,
I took the seats and carpet out a week or so ago and did a re-wire for all the amps,
I'm having a custom stereo facia made,
A sub is going under the tray between the front seats,
etc, etc.

Thanks guys.
