^ i dont think anyone knows for sure yet, if i can get my hands on the controls i would be more than happy to try it out for you.

i did look online and the part numbers for the main interior harness that goes to the stereo, steering wheel and all the other electrical components are actually different part numbers between the EX and LX but it is the entire harness under the dash so i have no clue what parts are actually different

OK, I found out the answer

Here's the DIY I found:

Yes i finally got it working! I told you I would get it to work even if i had to rewire the whole car. Here's what i did:
Ordered the following parts from the EX Model:
Steering Wheel audio controls ($78.32):
& The Wire Harness ($254.29):
Total of $332.61
Here's what i did to get it to work:
Audio controls installation:
Removed the Air bag from steering wheel
Removed the space holder plastic cover from the left side,
Removed the Cruise control switch, Now I the space ready to mount the Audio controls & the Cruise control Switch (It's one piece that's why you have to remove the existing cruise control switch).
Mount & connect the Audio controls & the Cruise control Switch, this is very easy to do because the connector is the same as the one you removed.
Connect the air bag make sure you screw in the appropriate screws and they're properly tighten. You're done with the control Switch!
Before you start Remove the Ground cable off your Battery!
Wire Harness Installation:
Lower & pull out the steering weel as far out and low as it could go.
Remove the top cover which is a snap out cover, the one on top the ignition switch, whiper switch, ligth switch, that TOP Cover, very easy to remove, (it snaps very easily) apply upward pressure to release it.
Remove the Audio/Cruise connector (The White 20 pin connector attached to the black plastic Reel spring cover) Your LX model should have seven color coded wires.
Remove the Radio from the dash board (Remember to remove the 2 screws that secure the radio from the bottom of the radio by the cigarret lighter) Follow the instructions on Page 4 on this pdf: http://collegehillshonda.com/instructions/8th_gen_civ_sedan/xmradio.pdf
Remove all radio connectors and look for the 20pin Grey connector that should have 6 color coded wires.
Remove the grey or black insulating tape that wraps all the cables for the GREY connector cables ONLY since you're going to cut them and pair them with the Grey connector from the EX wire harness.
Give at least 1.5inches of lag cable to the connectors before you cut them just in case you need to reuse them.
Cut the Grey connector from the radio side
Cut the White Connector from the steering wheel colum side
Now find the connectors both The White & the Grey on the Wire Harness and trace them to the other end by removing the black tape & the plastic protection. Cut all the wires from both end points and make sure you leave at least 7 inches of cabling. All cables should be color coded pair them accordingly and solder them. All Wires should be paired except for the 2 additional cables that are attached to each of the connectors.
Pair them accordingly to each en-point and solder them after you pair them. Use Electrical tape to cover each one of the open soldered points and cover all the cables nicely with more Electrical tape.
Do the same for both connector sides Grey & White.
Connect all end points and snap in all the covers (Don't forget the 2 screws for the RADIO).
And you're done!

Cool, but i have a question. My car (brazilian lxs 2007 at civic), does not have cruise controls. How do i know if my radio supports the steering wheel audio controls? Can someone show me a picture of the radio connectors to see if my radio have the connector for the ex wire harness?

Bump. I want to do this to MY 06 LX BUT I wonder if it will work with an aftermarket radio...chances are, the volume will but I don't know what the other two controls are (I can't quite make out the lettering on the pics Ive found). If anyone knows for sure, hit me up.

I just installed my PAC steering wheel control adapter and the 2 wires I only dealt with were PIN6 and PIN7. One of them is a brown grey striped and the other right beside it is Pink grey striped. I have an EX coupe so mine had the steering wheel controls built-in. That would be cool if you could pull off a mod like that though =)

no you can get the oem part from hondapartsnow.com and the removal dosent take that long just make sure that you disconnect the ground from you car batter so the airbag dosent go off. you only need to remove the dash to run the wires to the stereo
