Radio Harness Pin Outs?

[EuroSteve]

Hi All,

After searching these forums and a fair amount of googling, i'm still unsure about some of the pin-outs on the Euro radio harness.

I'm in the process of installing some gear (see http://ozhonda.com/forum/showthread.php?t=81596 and http://ozhonda.com/forum/showthread.php?t=81596) and have bought male and female wire harnesses so I can hook up my gear without cutting into the factory harness. The idea is to solder the two together and plug it inline with the factory harness.

Some photos:


As you can see from the second photo, 6 pins are missing from this harness for some reason, and i'm wondering what they might be for?

I refer you to one4spl's photo of his Euro's harness:


I see that the Euro is using 3 out of those 6 missing pins. Does anyone know what they are for?

So far, I beleive the pinouts are:
1: Ground
2: Dimmer
3: LF -ive
4: RF -ive
5: LR -ive
6: RR -ive
7: ?
8: ?
9: ?
10: ? (Used by the Euro)
11: +12V
12: Illum./Dash Lights
13: LF +ive
14: RF +ive
15: LR +ive
16: RR +ive
17: ? (Used by the Euro)
18: ? (Used by the Euro)
19: Ign/Switched +12V
20: Ant. Power

I need a connection to the steering wheel control wire, i'm guessing one of those ? wires is it...?

Cheers,
Steve

PS. I'm not sure if this thread is best suited here or in the Audio/Video section?

Hey EuroSteve, was wondering where you got your harness from? Is this an Aerpro harness? Whats the cost?

I want to do something similar. I just want to add a headunit, but use the factory speakers and dont want to cut the factory cable either.

Thats awesome, does that mean that we can do a convertion from non-satnav to satnav? or is there more connections involved

Sorry for the late reply.

I bought the male and female harnesses from eBay and soldered up the complete harness myself.

I honestly couldn't tell you. At the very least, I think you'd have to connect a GPS antenna.

It can be done. Someone in the US did that with their TSX, converting it from non-sat nav to sat nav.

Hi EuroSteve,

Thanks for the links, was just wondering if you had to add extra pin/cable into the harness to make up for the missing pin/connector/cable to retain stock connectivity to the stock head unit?

If Im reading the pins right and the picture of the connector. Looks like the connector will not connect back the sterring wheel controls or part of it?

Just need to make sure so I can buy double of everything and remove some pins/cable from the connector to the harness that has missing pins/connector/cable so all funtionality of the factory HU is retained.

Thanks.

Ahh yes, I forgot about that. For some reason, the harnesses I bought off eBay don't come fully populated with pins. Because I had no need for the speaker out from the HU, I used those pins to populate the missing ones that I needed.

Yeah, if you need to populate the whole connector, buying two, and using the pins from the 2nd one would be the best option.

You'll need a small "jewelers type" flat blade screw driver to remove the pins from the connector.

Awesome. Thanks for the info Steve. Yeah for me I'm satisfied with the stock speakers (I'm sure aftermarket would be better quality, obviously), cbf installing an amp and so on. So HU upgrade/addition and maybe headrest screens will be fine for me.

Thanks again.

Just wondering do you need to use all the connections? besides the nav unit if you have it that is.
and whats the best tool to use to crimp the wires into the harness and installing the pins?

Thanks all.

Tiny flathead should do the job to remove the pin/cable and you can reinstall it on the sockets that have a missing cable.
