hi all
thanks for the help and feedback.
Hiro Protagonist - I'm pretty sure there is no factory alarm in the car at the moment. It has central locking standard and the owner (I'm just doing the work for him) purchased a genuine toyota remote conversion kit for it. It wasn't hard to install, just that half of the instructions were completely wrong in terms of pointing out which connectors had the wires needed to be spliced. Yes, it could have been an hour's work easy, but trying to translate (english was fine, just the location of the connectors were totally way off!) the damn thing was a complete head f**k .
Then after installing it, I realised the remote that was supplied with the kit is a black one which is standard on the current shape rolla's (from 2003 - 2006, just b4 the new ones). According to the picture on the manual, it shows an older type rectangular-shaped remote with a big and small button which is getting me more confused.
so yeh.. will put it off until I get further clarification from spare parts of my dealership.
cheers
