hi mate all the wires that you have connected are all correct but the ones that you are stuck on are as follows
green/brown the flasher polarity is positive so connect to battery pos
green this one is the door circuit which you will pick up on the door switch drivers side which is brown/red
yellow this one is not needed
black/white inicators connect these to the black/green and black/white at the steering column, is this one wire or two if two you will need to use the diodes supplied with the alarm to make this output into two wires
If the diodes that come with your alarm are not labled then you will have a side with a stripe on this side must be connected to the the car side of the wiring and facing away from the alarm wiring
central locking
both of the common wires go to earth and you use the normally open outputs to the lock and unlock on the car which are the wires i tolc you about previously
Hope this helps mate
