Andrew997

Hi, I am new in Rennlist. Located in Madrid, Spain and owning a nice 997 that I bought 3 years ago, and with 60k miles as of today.
My unit is well equipped, missing a few things I do not need anyway like Bose sound system, electric seats, leather dashboard,..
But the one thing I really miss is the light and rain sensor. It is a hassle to have to manually turn the light switch every time I go in a tunnel. Or to have to change manually the speed of the wipers.
I have been thinking of retrofitting the sensor that costs some 350$ but I am not sure if the factory wiring is pre-installed and is just a plug-and-play upgrade.
Any views on this upgrade to help me?
Alternatively I have found a solution from autolightsystems.com called PALS, but I rather go the OEM route first.
Thanks in advance to all of you for any advice you can give me.
Cheers,
Andrés
Pd. I enclose the oem refs for the sensors and a photo tracking my 997.
