Right Way for Adding the auxiliary jack in to a 2006 Honda Civic

Adding the auxiliary jack in to a 2006 Honda Civic

Auxiliary jack  is an electro-mechanical device for joining electrical circuits as an interface using a mechanical assembly. Connectors consist of plugs (male-ended) and jacks (female-ended). 

Parts 

• 3.5mm jack. Can substitute for 2.5mm jack for mobile phone connections, or 6.5mm for the larger headphone plug.
• 3 pieces of wire of similar thickness to wire used by the stereo system, around 40 to 50cm, with crimp pins at one end, to connect the above jack to the stereo system. Adjust length according to where you want the jack to be located – above measurement if locating jack near cigarette lighter. 
• 1 piece of wire of similar thickness to above, around 10cm, with crimp pins on both ends. OR 2 pieces of wire of similar thickness to above, around 10cm, with crimp pins on one end, and twisted together on the other using a wire nut or crimp-on connector. This wire is used for looping the detection pins so that the AUX mode is activated on the system.

To save yourself the hassle of crimping the wires yourself, see if you can acquire a CDROM audio connector cable from computers, which look like this:
You can then remove the flat black connector (already removed in the picture), exposing the necessary crimped wire ends. The white connector isn’t useful in this case, so just cut it off and strip each wire.

11 Steps Right Way for Adding the auxiliary jack in to a 2006 Honda Civic

1. Strip the non-crimped end of the 3 wires to be connected to the jack, and twist the individual strands together per wire. Make note of which wire you are going to denote for left, right and ground – I used left (orange), right (purple), and ground (black).


2. Solder the 3 stripped wires to the appropriate terminal on the jack.  (Make sure you do a better soldering job than what I’ve done here; I have since had to redo it.) I added some tape around each solder joint to make sure the terminals don’t touch. Probably unnecessary.  If you’re unsure of what terminal does what, connect the jack to a 3.5mm-3.5mm audio cord, and use a multimeter to test by placing one testing prod on the jack, and the other on various parts of the connected 3.5mm audio cord. The diagram below will help you identify which part of the 3.5mm audio plug does what:


3. Thread the newly created jack and wire from the audio system hole, to the hole in the compartment next to the cigarette lighter, or wherever you want it to be.

4. Now find system connector #2 (see above for pictures), and unlock the pin slots by prying open the locking mechanism (see below) slightly – do not remove the locking mechanism as you won’t be able to insert the wires for the top row of pins. Use the slit shown below to pry it upwards.


5. Now insert the jack’s ground wire into the AUXSH (AUXiliary SHield ground) position AUXSG (AUXiliary Shield Ground) position, the left wire into the AUXL (AUXiliary Left), and the right wire into the AUXR (AUXiliary Right) position. (The previous version of this document incorrectly stated that the ground wire should go into AUXSH; it should instead go into AUXSG. If you use AUXSH, the audio will sound soft, far away, out of balance, and you may notice some elements of the song to be missing or very, very soft.) These names refer to the annotated connector diagram above. Note that that diagram shows and numbers the pins as though you are looking at the end of the connector that goes into the audio system, not the end where the wires are inserted. Make sure they are inserted all the way in – they do fit into the entire width of the connector, from the insertion end, to the pin contact end. You can visually check to see if they’re in far enough by looking at the pin contact end. Ensure you don’t dislodge the existing 2 wires either (pink and brown).


6. To activate the AUX mode on the system, insert one end of the remaining looping wire into the AUXD (AUXiliary Detection) position and the other into the AUXG (AUXiliary Ground?) position. Your system connector #2 should look like this now:


7. Confirm the wires are in the right position and inserted far enough, then secure the locking mechanism by pushing it back into its original spot.

8. Reconnect up the audio part of your dash, and test! Your CD changer (if your system has one) will take a minute to detect and reorganize itself after losing power. To enter AUX mode, press the CD/AUX button twice; once enters the CD/CD Changer mode.

If it doesn’t work, confirm you have the right pin positions and that the pins are inserted far enough.

9. At this point you may want to drill a hole and mount the jack somewhere. I drilled a hole and mounted mine underneath the cigarette lighter socket. If you do intend to do this in that location, be warned that the 
plastic there is fairly thick. In my case it was thicker than the threaded section of my audio jack, so I couldn’t screw the nut on to secure it. Luckily, the hole I drilled was tight enough to hold the jack in place without it.

10. Use cable ties to tie up the new wires and/or tape them up.

11. Replace the audio part of the dash, test, and if it works, have fun putting all the other parts back into place! Again, they some require a bit of a push to get back into place, and don’t forget the screws.
