Was there ever a plug for the outlined socket? I reverted my unit back to stock but couldn't find the plug for the outlined socket. Now, my Aux and DISP features have stopped working. I suspect its because I didn't connect it. Can anyone confirm if there was a plug for it? Thanks

 

there is a plug for the sport model, that is what links the ipod jack to the radio and causes aux to function. that is also the connection that I had to solder to in order to connect my ipod jack to the radio on my base fit, so if you have a sport, there should be a connection for it.

edit: actually, sorry, its the one to the right of the highlighted one. I am pretty sure the outlined one is plugless, but i am unsure as I have a base. double check the cable to the right of it is securely in, it is the one that controls aux. also double check the harness is plugged into the ipod jack under the center console

 

woot It's working. Thanks jaebee.

DISP however is still not working. When I press it nothing happens

 

glad to hear that worked. i have no help for the display tho... maybe try the radio code? i dont know, I would just double check that all the plugs are in tight, as some of them were a bitch to unplug / plug back in. the harness for the radio is fairly compact, meaning no plugs should have been able to dissapear into the car.

good luck to you!
