no that wont work apple - the kits you buy off ebay are remote central locking kits, e,g, they add the remote to existing cental locking
if youve bought an S or SX cinq/sei then you can rob the bits off a sporting in a scrappers
i have done this to my old cinq s (well big bro did
)
my bro is very competent with auto-electrics as hes been working in a car electrics place for like 5 years - between us it took us about 3 hours to strip the car at the scrappers nearly giving up on several occasions - then it took a further 3 or 4 hours to fit at home.
the electric windows and central locking units are quite intermingled so you cant fit one and not the other
basically you have to remove all of the innerds of both doors and replace with electric runners and electriconic servo thingy ma bobs for the door pins
then run all the cabling through the door hinge area and bring them to the passenger footwell where central locking units etc needed to be fitted - oh and then wires run to the buttons which replace the spare blanking plates next to the stereo
there may be a thread about how my bro did this in more detail somewhere
if your not competent at electrics i wouldnt attempt it really
