Honda OEM Cd player add-on unit

I got a slave-cd add on off ebay. it's a honda oem unit for connecting to a honda oem tape deck. the P/N is 08A06-121-210, rhe REF.NO is CD2102. i have a feeling it miiiight not work, as this one has controls and i believe my head unit is designed for a player that doesn't have controls. anyway, the round plug thing plugs into the headunit, i got that far, then it's got 6 wires on it, the guy i bought it from wasn't sure what they were for

black (obviously ground)
white
yellow w/ red stripe
orange
white w/ blue stripe
brown

I have no idea what kind of car it came out of, it has play/pause and previous/next buttons built in, so I'm thinking accord or civic before 1996? I called a honda dealer but their parts department couldn't help since I didn't have the car type. Any ideas or should I try my luck selling it to someone who knows what they're doing on ebay?

could anyone shed some light? hopefully i've not alread fried it experimenting

edit: I have reason to believe this unit came out of an 1989 to 1993 accord.
