Fitting After Market Double Din Stereo?

[William Taylor]

Basically I have brought a Xtrons double din, and too b honest haven't been all that fussed about getting in the car until yesterday when drove from London to Japfest, and man that was a long old drive. That and I'm a complete noob to stereos as this will be my first car with one in Ha, original my EP3 came with the Honda stereo but needed the code, so I didn't bother. Then when I have taken it out ( and this is where my problem is ) the bloke who had it before has done some real dodgy wiring in there using electrician connectors, and I haven't got a clue what each wire is? Basically I'm after colour coding on the Honda's stereo wires?

And if there is any other issues other's may have encountered on fitting double dins?
