6th gen radio help

[vtec11087]

So ive spent the last hour trying to fix my mothers 1999 Civic's CD player. Its an LX with the stock radio and a 6 disk CD changer in the back trunk. The radio works fine but when i press the "CD/Tape" button on the dash to switch to the 6 disk CD changer it does nothing and the radio just keeps playing. (The CD disk changer used to work fine, but hasnt for the last month or so all of a sudden) I've got the whole damn dash taken apart and the center console/climate control/radio out too hoping i could find something, but nothing. Only thing i have noticed is that on the back of the factory radio are two plug in boxs, but only one was plugged in. I searched for maybe a loose plug somewhere which would activate the CD/Tape but found nothing at all behind the dash. Is this just how the back of stock 6th radios are?

Damn 6th gen's.
I've been bamboozled.

hmm dunno if this relates but my g/f had a stock radio in her probe with a cd changer and the cord got pinched we finally discovered.

goodluck

is the changer getting power? meaning does it load and unload the catridges? take out the deck and make sure its plugged in in the back...sounds to me like the headunit does "see" the changer

Make sure that the CD changer is plugged to the radio

Thats it exactly Solidsnake, the bus harness is missing.
But ive searched all over the interior/dash for a loose harness and have found nothing... but thanks that helps alot now that i can identify what im needing.

These are the instructions to install the CD changer in a Sedan. this will show you how the BUS wire is supposed to be routed.
