you dont need to go lahore...in my opinion have this type of work done from your own city,just go to Bismillah car decoration or City car decoration at jail road, ask him for security system do some negotiation buy it electrition will install it,and you are all done.....but keep both eyes on installer (you may take friend with you) so he will not try to be over smart while fiddling with electrical system of your brand new car.............drive safe
