Help needed to fitting a Toad A850 car alarm
 

Hi, I just bought a Toad A850 car alarm. It didn't come with any
fitting instructions. I think I have worked out what most the cable
are for by looking at the fitting instructions for a Ai606. but i have
4 wires left over that I do not know what they are for.

orange
purple
blue/white
brown/black

They must be something to do with the central locking/transmitter
function. Any advise or help would be appreciated.
If any one has a wiring diagram for this model that would be helpfull.

Thanks
