install plug for aftermarket stereo in 06 DX
 

does anyone make a install plug to put a aftermarket stereo in an 06 DX, I think the plugs are different between each of the models but when I look up online they only show one plug like its supposed to fit all models????? I bought a factory stereo cd unit from an EX or LX off ebay but it won't plug in, the wiring harness plug is different. so now I want to put in an aftermarket stereo but can't figure out the harness issue?????[:@]
