Hi all, Newbie to the forum here and already need advice!! Ive read some of the fitting advice on the forum and now Im fitting central locking to my 99 td5 myself, fitting is not a problem,wiring it up is! where can i wire up to? do i go straight from the battery for power or behind fuse panel or go from ECU? could it be matched up to my immobiliser key fob? This is my first td5 and ive not been used to my landy having a brain!!! Ha Ha.. :D
