[Abelnut]

Hi All,
Can anybody help me with the above, the car has key only operated c/locking and i am trying to install a universal unit to use fobs, i have purchased
a haynes manual for the wiring diagram but it seems wrong/incomplete, any ideas were i can get a factory diagram or has anybody managed to wire one of these kits to this shape model.
thanks
