Aren't all 8-pin cords the same, Honda?

Hi,I bought a Honda cd changer from ebay for my girlfriend's'97 Civic. I won't be able to test it for a couple ofdays, so I thought I'd test it in my '92 Integra first, because the back of my stock deck had the 8-pin input. I'm not sure if the tape deck has cd functions or not,but it has the input, and the bottom of the deck saysit's for an equalizer, a changer, or the little plug.For some reason, it won't fit in my deck. I figured all the 8-pin round cords were the same. Here's some pics below:Here's the back of the stock deck:

Here's the cord from the changer:

Here's the extra cord that came with it:

Shouldn't this fit my teg?

Thanks!

If the front of the head unit does not cd or something like that tthen it will not work.  It must have a button to switch to changer mode.  Most likely in your car that is for an iso-mount.  Radio only on top and just cd on bottom, not changermatrixman
