Another DIY: Honda Homelink

Re: Another DIY: Honda Homelink
It will be interesting to see what the pinouts of the connector are for a Navi/Homelink module. Be sure to check that the microphone connections are the same, especially Pin 5.
On the setup I got, pin 5 was used for the Homelink power, but the Civic had that pin as one of the 3 microphone leads. All of the other leads will be OK.

Re: Another DIY: Honda Homelink
I have a 2007 Honda Odyssey w/Nav. I'll examine the 5 pin connectors, compare it's pinout to the 2008 HCH II.
Ya gotta think they'd pinout the same, but I guess not.
Either way, a quick swapping of pins should fix it.

Got the module (ody with nav), swapped in a blue led, and tested it in the wifes van. All of that works great. The setups look identical to your photos.
When I compare harnesses the Civic has 3 wires the Odyssey has 6. Clearly, 2 of the "new" wires are illum +/-... and of course the other is switched power... that's all I can figure out at this point.
What's really throwing me for a loop is the ody mic has only 2 leads going to it, not 3. Where that 3rd red wire going to on yours?
Without a wiring diagram, I'm shooting in the dark here.
Could you line out for me the pinouts of the Ody overhead console and the civic overhead console?
I'm usually pretty handy, I just haven't bought these manuals yet.
I'd appreciate the help.
FYI, the pinout for the Ody is as follows:
1 - blank
2 - blank
3 - thin gauge pink (mic signal +)?
4 - thin gauge blue (mic signal -)?
5 - white/ blue -?
6 - black (ground)
7 - red/black stripe - (illum) +
8 - blank
9 - blank
10 - green/red ???

Re: Another DIY: Honda Homelink
Chris:
It looks like the Mic that came with your Odyssey is different from the one that the Civic uses.
Here is the difference between your Homelink module and the Civic connector:
1 - blank same as Civic.
2 - blank same as Civic.
3 - thin gauge pink (mic signal +)? same as Civic.
4 - thin gauge blue (mic signal -)? same as Civic, but Civic wire is brown.
5 - white/ blue -? On Odyssey, this is Homelink + power, on Civic this is Mic white wire. On my setup I re-routed this mic wire to pin 9. For the Homelink power, I tapped a unswitched fuse location.
6 - black (ground) Homelink -, not used on Civic, so Civic harness needs this additional wire.
7 - red/black stripe - (illum) + not used on Civic, so Civic harness needs this additional wire. I ran this lead to a low-beam headlight fuse so the LED would be switched.
8 - blank same as Civic.
9 - blank This is the pin I re-routed the pin 5 microphone lead to.
10 - green/red ??? ambient light ground.
Hope this helps.

Re: Another DIY: Honda Homelink
Thanks...
Very helpful.
This kinda stinks, you'd think the microphones would be the same...
Looks like I'm gonna have to farm over the old microphone to make this work, since it appears the Civic uses a 3- wire mic opposed to the Ody's 2 -wire.
Could you discuss where you soldered the the leads of the of the mic to? I can kinda see 2 of them (, but what the red wire going to)?
After tracing the pins, I think I get it now...
If you relo'd pin 5 to pin 9 - it apears you connected that trace to the blob "solder sqaure" as part of the interface. So to verify:
Mic pins:
- pin 3 - black
- pin 4 - green
- pin 5 - white, relo'd to pin 9 , and connect to the solder blob square?
Sorry to be so needy. The good news is, once I figue this out in the public forums, the next guy to come along will be able to follow suit.

For the relocation of the Pin 5 mic wire
I think that the extra wire on the Civic microphone is a lead to the noise compensating volume control on the radio.
So for the relocation of the pin 5 mic wire. The reason I chose to use pin 9 to relocate it, is that if you follow the pin 9 circuit trace on the Homelink circuit board, you will see that there is quite a lot of area that is available to solder the 3rd microphone wire to. Pick a spot, the square solder blob is fine.
Sounds like you are in the right direction.
One other thing, when you relocate the Civic mic to the Odyssey Homelink assembly, you will need to trim off the 2 spacer bars on the microphone receiver clip so the mic can fit flush on the assembly. This will be obvious when you put everything back together and see that the mic is sitting too high to get the trim bezel back on.

Re: Another DIY: Honda Homelink
Mic successfully transferred.
Gotta run my illum wire, and switched power, then I'll be done. Gonna do that next weekend, when I install the BlueConnect.
Gary, thanks a lot for the help. I know the Homelink and LED functions work, I tested them in the van. Just ran out of time today to run that wiring.
I'm NOT gonna wire to the constant 12V in the headliner... for one reason alone. If someone busts the window to steal my petty change, and has a bright idea to hit the homelink button... my garage opens.
... dn that's where the good stuff is.
Since I gotta run a a constant 12V, switched 12v and ground for the blueconnect, I'll just splice off those.
BTW, again...
I have a spare Odyssey homelink module if anyone wants one. - $80 delivered.
If anyone else wants to do it
