hi i bought a boss bv9980 flip out touch screen for 180 for my 2002 bmw 325i and i got everythng for it but the front illumination wire tht leads into the plug that connects the wiring to the indash stereo is out. All the other wires are clippd in some way to the plug head but this wire came out somehow and the unit wont turn on without this being in. Depending on how i move the wire the little screen flicks on and off. Is there anyway to put this wire back in to the plug? I need to find a way or this system will not turn on please help thank you
