Help needed with RSE retro fit

[daviesbike]

Calling apon any one with RSE knowledge. ..

I have retro fitted rear seats with screens. Wired them up I have wired up the Aux in and headphone jacks in the rear and routed the fiber optic network to it ..

Im stuck in that the dvd changer has 3 main leads on it two identical red ones and a small brown one .
There is a slot in the tv tuner for the red one but not two red ones only one.. im wandering is there another box im missing to plug the othes in..

Cant help but think they cant just dangle there

Any help ..or pictures and diagrams would be great.. the Alpine manual is far from help full

Thanks Guys..

Also I have the mmi remote how do I sync it ?
And are the rear screens suposes to replicate the mmi screen when not playing a dvd ? Because mine are just blank at the moment and there is not settings in the mmi for anything in the RSE ?
