deck aux?

[sexualbanana]

so i have myself a alpine cda-7875. i'm trying to get at the aux cords, but i can't seem to find them. i think there might be an extension that's sold seperately to get the aux cords, but i dunno. i think that it could just be hidden somewhere behind the deck and i just can't see it behind all the wires and stuff.

i think i might have seen the aux cords when it was being installed, but i can't remember since it was like 8 months ago
