sony XAV-7W dvd head unit

dont get me wrong i'm a dab hand at stereos and most car electrics but when i bought the golf the company who fitted the sound system made it look like it was fitted by kids I.E wires twisted and taped, instead of moving the carpets they cut through both front and rear! and to make things worse the lad who i got it off hadnt a clue he riped the sound system out and left LIVE wires hanging!                                                             

problem is he gave me all the sound system which i sold exept the dvd head unit and with no book i have no idea what wire is for what??                 

got live switch earth remote etc but i need to know which is the parking brake feed? (to stop it being used while driving) which will just be a switchabe live if i can figure it out,  has any one had one or know where i can get a diagram from? tried google

thanks pete

Live feed for that should be a solid grey wire.

cool i'll have a look when i can find the plug, there were two head units running off 1 set of plugs, if it was me i'd have used the plug for the main h/u (sony media controal unit) and wired the other h/u seperatley instead of that bodge that they did.
