you just need the correct wiring harness for it. meaning, if you have a Pioneer headunit, you must find a Pioneer wiring harness. if you had a stock OEM cd player before, you have to buy a Honda wiring harness also. here's how it would connect from the car to the headunit. it's not that hard to wire them together. it's basically matching the color. the blue and white strips (i believe) is the remote which you wire that to the amp if you have subs. hope this helps or hope this is what you're talking about.
