Try this, I have no clue beyond that.... If you find the both cables, you're wired, now you need to figure out your changer. Perhaps some one smarter can chime in, maybe there is an adapter you need? And also keep in mind that if you have DSP, you will not have a 6 pin connector, instead you will have a coax cable. Just look behind the liner, under the insulation, cut the plastic tie that has your cables tangled together....
I'm out.
