RE-WIRING PHILIPS CAR 400 STEREO?

I HAVE RECENTLY BOUGHT A '98 VECTRA. THE ORIGINAL STEREO IS IN THE CAR BUT NOT CONNECTED, ALL THE WIRES HAVE BEEN CUT AND THERE IS NO JACKS ON THE BACK OF THE STEREO. ANYONE HAVE A WIRING DIAGRAM SO I CAN CONNECT IT BACK UP? ALSO , THERE IS A CD MULTI CHANGER IN THE CAR, BUT I AM LEAD TO BELIEVE THIS DIDNT COME WITH THE CAR 400 STEREO, IS THIS CORRECT? THE WIRING DIAGRAM WOULD BE MUCH APPRECIATED. THANKS
