Hello I'm new to this forum, I recently bough a 2003 TL (non type s) and I want to add the oem keyless entry system that is available on the Type S.

I was wondering, is there just a module that I can buy and put it on, or does it still require for me to go around and find each wire (key, lights, ignition, etc) to install it. I know the car has some type of built in security system already, that is why i'm wondering if the steps are still the same as installing any regular alarm or no.
