there are two spots for plugs on my si deck
one for the factory stereo plug and then another
the reason i ask is because after looking at crutchfield's site for i-pod adapters
i found one, but it says that the factory radio must have cd changer port
now i always thought those were thick round cables
does the other spot for a plug work for a cd changer
thanks in advance

newer hondas no longer use the round din connector; instead, it could be the rectangular-ish molex one.

 

yes the empty plug is for another source.

 

is there a wiring diagram for this plug
looks like maybe you could just use an "rca inverter"(think that's what that's called)
and possibly make your own i-pod adapter
